M20 Peptidase beta-alanine synthase, an amidohydrolase; Peptidase M20 family, beta-alanine synthase (bAS; N-carbamoyl-beta-alanine amidohydrolase and beta-ureidopropionase; EC 3.5.1.6) subfamily. bAS is an amidohydrolase and is the final enzyme in the pyrimidine catabolic pathway, which is involved in the regulation of the cellular pyrimidine pool. bAS catalyzes the irreversible hydrolysis of the N-carbamylated beta-amino acids to beta-alanine or aminoisobutyrate with the release of carbon dioxide and ammonia. Also included in this subfamily is allantoate amidohydrolase (allantoate deiminase), which catalyzes the conversion of allantoate to (S)-ureidoglycolate, one of the crucial alternate steps in purine metabolism. It is possible that these two enzymes arose from the same ancestral peptidase that evolved into two structurally related enzymes with distinct catalytic properties and biochemical roles within the cell. Downstream enzyme (S)-ureidoglycolate amidohydrolase (UAH) is homologous in structure and sequence with AAH and catalyzes the conversion of (S)-ureidoglycolate into glyoxylate, releasing two molecules of ammonia as by-products. Yeast requires beta-alanine as a precursor of pantothenate and coenzyme A biosynthesis, but generates it mostly via degradation of spermine. Disorders in pyrimidine degradation and beta-alanine metabolism caused by beta-ureidopropionase deficiency (UPB1 gene) in humans are normally associated with neurological disorders.

M20 Peptidase T like enzymes specifically cleave tripeptides; Peptidase M20 family, PeptT (tripeptide aminopeptidase; tripeptidase)-like subfamily. This group includes bacterial tripeptidases as well as predicted tripeptidases. Peptidase T acts only on tripeptide substrates, and is thus called a tripeptidase. It catalyzes the release of N-terminal amino acids with hydrophobic side chains from tripeptides with high specificity; dipeptides, tetrapeptides or tripeptides with the N-terminus blocked are not cleaved. Tripeptidases are known to function at the final stage of proteolysis in lactococcal bacteria and release amino acids from tripeptides produced during the digestion of milk proteins such as casein.

ArgE catalyzes a broad range of substrates, including N-acetylornithine, alpha-N-acetylmethionine and alpha-N-formylmethionine, while DapE catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelate (L,L-SDAP) to L,L-diaminopimelate and succinate. Proteins in this family are mostly bacterial and have been inferred by homology as being related to both ArgE and DapE. This family also includes N-acetyl-L-citrulline deacetylase (ACDase; acetylcitrulline deacetylase), a unique, novel enzyme found in Xanthomonas campestris, a plant pathogen, in which N-acetyl-L-ornithine is the substrate for transcarbamoylation reaction, and the product is N-acetyl-L-citrulline. Thus, in the arginine biosynthesis pathway, ACDase subsequently catalyzes the hydrolysis of N-acetyl-L-citrulline to acetate and L-citrulline.

M28 Zn-peptidases include aminopeptidases and carboxypeptidases; Peptidase M28 family (also called aminopeptidase Y family) contains aminopeptidases as well as carboxypeptidases. They have co-catalytic zinc ions; each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. The aminopeptidases in this family are also called bacterial leucyl aminopeptidases, but are able to release a variety of N-terminal amino acids. IAP aminopeptidase and aminopeptidase Y preferentially release basic amino acids while glutamate carboxypeptidase II preferentially releases C-terminal glutamates. Plasma glutamate carboxypeptidase (PGCP) and glutamate carboxypeptidase II (NAALADase) hydrolyze dipeptides. Several members of the M28 peptidase family have PA domain inserts which may participate in substrate binding and/or in promoting conformational changes, which influence the stability and accessibility of the site to substrate. These include prostate-specific membrane antigen (PSMA), yeast aminopeptidase S (SGAP), human transferrin receptors (TfR1 and TfR2), plasma glutamate carboxypeptidase (PGCP) and several predicted aminopeptidases where relatively little is known about them. Also included in the M28 family are glutaminyl cyclases (QC), which are involved in N-terminal glutamine cyclization of many endocrine peptides. Nicastrin and nicalin belong to this family but lack the amino-acid conservation required for catalytically active aminopeptidases.

M20 Peptidase Xaa-His dipeptidase (PepV) degrades hydrophobic dipeptides; Peptidase M20 family, Peptidase V (Xaa-His dipeptidase; PepV g.p. (Lactobacillus lactis); X-His dipeptidase; beta-Ala-His dipeptidase; carnosinase) subfamily. The PepV group of proteins is widely distributed in lactic acid bacteria. PepV, along with PepT, functions at the end of the proteolytic processing system. PepV is a monomeric metalloenzyme that preferentially degrades hydrophobic dipeptides. The Streptococcus gordonii PepV gene is homologous to the PepV gene family from Lactobacillus and Lactococcus spp. PepV recognizes and fixes the dipeptide backbone, while the side chains are not specifically probed and can vary, rendering it a nonspecific dipeptidase. It has been shown that Lactococcus lactis subspecies lactis (L9) PepV does not hydrolyze dipeptides containing Pro or D-amino acids at the C-terminus, while PepV from Lactobaccilus has been shown to have L-carnosine hydrolyzing activity. The mammalian PepV also acts on anserine and homocarnosine (but not on homoanserine), and to a lesser extent on some other aminoacyl-L-histidine dipeptides. Also included is the Staphylococcus aureus metallopeptidase, Sapep, a Mn(2+)-dependent dipeptidase where large interdomain movements could potentially regulate the activity of this enzyme.

Zinc peptidases M18, M20, M28, and M42; Zinc peptidases play vital roles in metabolic and signaling pathways throughout all kingdoms of life. This hierarchy contains zinc peptidases that correspond to the MH clan in the MEROPS database, which contains 4 families (M18, M20, M28, M42). The peptidase M20 family includes carboxypeptidases such as the glutamate carboxypeptidase from Pseudomonas, the thermostable carboxypeptidase Ss1 of broad specificity from archaea and yeast Gly-X carboxypeptidase. The dipeptidases include bacterial dipeptidase, peptidase V (PepV), a non-specific eukaryotic dipeptidase, and two Xaa-His dipeptidases (carnosinases). There is also the bacterial aminopeptidase, peptidase T (PepT) that acts only on tripeptide substrates and has therefore been termed a tripeptidase. Peptidase family M28 contains aminopeptidases and carboxypeptidases, and has co-catalytic zinc ions. However, several enzymes in this family utilize other first row transition metal ions such as cobalt and manganese. Each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. The aminopeptidases in this family are also called bacterial leucyl aminopeptidases, but are able to release a variety of N-terminal amino acids. IAP aminopeptidase and aminopeptidase Y preferentially release basic amino acids while glutamate carboxypeptidase II preferentially releases C-terminal glutamates. Glutamate carboxypeptidase II and plasma glutamate carboxypeptidase hydrolyze dipeptides. Peptidase families M18 and M42 contain metallo-aminopeptidases. M18 is widely distributed in bacteria and eukaryotes. However, only yeast aminopeptidase I and mammalian aspartyl aminopeptidase have been characterized in detail. Some M42 (also known as glutamyl aminopeptidase) enzymes exhibit aminopeptidase specificity while others also have acylaminoacyl-peptidase activity (i.e. hydrolysis of acylated N-terminal residues).

M20, M18 and M42 Zn-peptidases include aminopeptidases and carboxypeptidases; This family corresponds to the MEROPS MH clan families M18, M20, and M42. The peptidase M20 family contains exopeptidases, including carboxypeptidases such as the glutamate carboxypeptidase from Pseudomonas, the thermostable carboxypeptidase Ss1 of broad specificity from archaea and yeast Gly-X carboxypeptidase, dipeptidases such as bacterial dipeptidase, peptidase V (PepV), a eukaryotic, non-specific dipeptidase, and two Xaa-His dipeptidases (carnosinases). This family also includes the bacterial aminopeptidase peptidase T (PepT) that acts only on tripeptide substrates and has therefore been termed a tripeptidase. These peptidases generally hydrolyze the late products of protein degradation so as to complete the conversion of proteins to free amino acids. Glutamate carboxypeptidase hydrolyzes folate analogs such as methotrexate, and therefore can be used to treat methotrexate toxicity. Peptidase families M18 and M42 contain metallo-aminopeptidases. M18 (aspartyl aminopeptidase, DAP) family cleaves only unblocked N-terminal acidic amino-acid residues and is highly selective for hydrolyzing aspartate or glutamate residues. Some M42 (also known as glutamyl aminopeptidase) enzymes exhibit aminopeptidase specificity while others also have acylaminoacyl-peptidase activity (i.e. hydrolysis of acylated N-terminal residues).

N-terminal acetylation of proteins is a widespread and highly conserved process that is involved in the protection and stability of proteins. Several types of aminoacylases can be distinguished on the basis of substrate specificity; substrates include indoleacetic acid (IAA) N-conjugates of amino acids, N-acetyl-L-amino acids and aminobenzoylglutamate. ACY1 breaks down cytosolic aliphatic N-acyl-alpha-amino acids (except L-aspartate), especially N-acetyl-methionine and acetyl-glutamate into L-amino acids and an acyl group. However, ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. ACY1 may also play a role in xenobiotic bioactivation as well as in the inter-organ processing of amino acid-conjugated xenobiotic derivatives (S-substituted-N-acetyl-L-cysteine). ACY1 appears to physically interact with Sphingosine kinase type 1 (SphK1) and may influence its physiological functions; SphK1 and its product sphingosine-1-phosphate have been shown to promote cell growth and inhibit apoptosis of tumor cells. Strong expression of the human gene and its mouse ortholog Acy1 in brain, liver, and kidney suggest a role of the enzyme in amino acid metabolism of these organs.

M28 Zn-Peptidase Plasma glutamate carboxypeptidase; Peptidase M28 family; Plasma glutamate carboxypeptidase (PGCP; blood plasma glutamate carboxypeptidase; EC 3.4.17.21) subfamily. PGCP is a 56kDa glutamate carboxypeptidase that is mainly produced in mammalian placenta and kidney, the majority of which is thought to be secreted into the bloodstream. Similar proteins are also found in other species, including bacteria. These proteins contain protease-associated (PA) domain inserts between the first and second strands of the central beta sheet in the protease-like domain. The PA domains may participate in substrate binding and/or promoting conformational changes, which influence the stability and accessibility of the site to substrate. The exact physiological substrates of PGCP are unknown, although this enzyme may play an important role in the hydrolysis of circulating peptides. Its closest homolog encodes an important brain glutamate carboxypeptidase II (NAALADase) identical to the prostate-specific membrane antigen (PSMA), which serves as a marker for prostatic cancer metastasis. Hypermethylation of PGCP gene has been associated with human bronchial epithelial (HBE) cell immortalization and lung cancer. PGCP also provides an attractive target for serological analysis in hepatitis C virus (HCV)-induced hepatocellular carcinoma (HCC) patients.

ACY1 is the most abundant of the aminoacylases, a class of zinc binding homodimeric enzymes involved in the hydrolysis of N-acetylated proteins. It is encoded by the aminoacylase 1 gene (Acy1) on chromosome 3p21 that comprises 15 exons. N-terminal acetylation of proteins is a widespread and highly conserved process that is involved in the protection and stability of proteins. Several types of aminoacylases can be distinguished on the basis of substrate specificity; substrates include indoleacetic acid (IAA) N-conjugates of amino acids, N-acetyl-L-amino acids and aminobenzoylglutamate. ACY1 breaks down cytosolic aliphatic N-acyl-alpha-amino acids (except L-aspartate), especially N-acetyl-methionine and acetyl-glutamate into L-amino acids and an acyl group. However, ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. ACY1 may also play a role in xenobiotic bioactivation as well as the inter-organ processing of amino acid-conjugated xenobiotic derivatives (S-substituted-N-acetyl-L-cysteine). ACY1 appears to physically interact with Sphingosine kinase type 1 (SphK1) and may influence its physiological functions; SphK1 and its product sphingosine-1-phosphate have been shown to promote cell growth and inhibit apoptosis of tumor cells. Strong expression of the human gene and its mouse ortholog Acy1 in brain, liver, and kidney, suggest a role of the enzyme in amino acid metabolism of these organs. Defects in ACY1 are the cause of aminoacylase-1 deficiency (ACY1D), resulting in a metabolic disorder manifesting encephalopathy and psychomotor delay.

M20 Peptidases with similarity to acetylornithine deacetylases and succinyl-diaminopimelate desuccinylases; Peptidase M20 family, uncharacterized protein subfamily with similarity to acetylornithine deacetylase/succinyl-diaminopimelate desuccinylase (ArgE/DapE) subfamily. This group includes the hypothetical protein ygeY from Escherichia coli, a putative deacetylase, but many in this subfamily are classified as unassigned peptidases. ArgE/DapE enzymes catalyze analogous reactions and share a common activator, the metal ion (usually Co2+ or Zn2+). ArgE catalyzes a broad range of substrates, including N-acetylornithine, alpha-N-acetylmethionine and alpha-N-formylmethionine, while DapE catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelate (L,L-SDAP) to L,L-diaminopimelate and succinate. Proteins in this subfamily are mostly archaeal, and have been inferred by homology as being related to both ArgE and DapE.

M20 Peptidases, Poly(aspartic acid) hydrolase-like proteins; Peptidase M20 family, Poly(aspartic acid) hydrolase (PAA hydrolase)-like subfamily. PAA hydrolase enzymes are involved in alpha,beta-poly(D,L-aspartic acid) (tPAA) biodegradation. PAA is being extensively studied as a replacement for commercial polycarboxylate components since it can be degraded by enzymes from isolated tPAA degrading bacteria. Thus far, two types of PAA degrading bacteria (Sphingomonas sp. KT-1 and Pedobacter sp. KP-2) have been investigated in detail; the former can completely degrade tPAA of low-molecular weights below 5000, while the latter can degrade high molecular weight tPAA to release oligo(aspartic acid) (OAA) as a product, suggesting two kinds of PAA degrading enzymes. It has been shown that PAA hydrolase-1 from Sphingomonas sp. KT-1 hydrolyzes beta,beta-aspartic acid units in tPAA to produce OAA, and it is suggested that PAA hydrolase-2 hydrolyzes OAA to aspartic acid. Also included in this family is Bradyrhizobium 5-nitroanthranilic acid (5NAA)-aminohydrolase (5NAA-A), a biodegradation enzyme that converts 5NAA to 5-nitrosalicylic acid; 5NAA is a metabolite secreted by Streptomyces scabies, the bacterium responsible for potato scab, and metabolized by Bradyrhizobium species strain JS329.
