M20 Peptidase Aminoacylase 1 family; Peptidase M20 family, Aminoacylase 1 (ACY1; hippuricase; acylase I; amido acid deacylase; IAA-amino acid hydrolase; dehydropeptidase II; N-acyl-L-amino-acid amidohydrolase; EC 3.5.1.14) subfamily. 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.

IAAspH hydrolyzes indole-3-acetyl-N-aspartic acid (IAA or auxin) to indole-3-acetic acid. Genes encoding IAA-amidohydrolases were first cloned from Arabidopsis; ILR1, IAR3, ILL1 and ILL2 encode active IAA- amino acid hydrolases, and three additional amidohydrolase-like genes (ILL3, ILL5, ILL6) have been isolated. In higher plants, the growth regulator indole-3-acetic acid (IAA or auxin) is found both free and conjugated via amide bonding to a variety of amino acids and peptides, and via an ester linkage to carbohydrates. IAA-Asp conjugates are involved in homeostatic control, protection, storing and subsequent use of free IAA. IAA-Asp is also found in some plants as a unique intermediate for entering into IAA non-decarboxylative oxidative pathway. IAA amidohydrolase cleaves the amide bond between the auxin and the conjugated amino acid. Enterobacter agglomerans IAAspH has very strong enzyme activity and substrate specificity towards IAA-Asp, although its substrate affinity is weaker compared to Arabidopsis enzymes of the ILR1 gene family. Enhanced IAA-hydrolase activity has been observed during clubroot disease in Chinese cabbage. Pssm-ID: 349938 [Multi-domain] Cd Length: 376 Bit Score: 227.97 E-value: 2.74e-71

IAAspH hydrolyzes indole-3-acetyl-N-aspartic acid (IAA or auxin) to indole-3-acetic acid. Genes encoding IAA-amidohydrolases were first cloned from Arabidopsis; ILR1, IAR3, ILL1 and ILL2 encode active IAA- amino acid hydrolases, and three additional amidohydrolase-like genes (ILL3, ILL5, ILL6) have been isolated. In higher plants, the growth regulator indole-3-acetic acid (IAA or auxin) is found both free and conjugated via amide bonding to a variety of amino acids and peptides, and via an ester linkage to carbohydrates. IAA-Asp conjugates are involved in homeostatic control, protection, storing and subsequent use of free IAA. IAA-Asp is also found in some plants as a unique intermediate for entering into IAA non-decarboxylative oxidative pathway. IAA amidohydrolase cleaves the amide bond between the auxin and the conjugated amino acid. Enterobacter agglomerans IAAspH has very strong enzyme activity and substrate specificity towards IAA-Asp, although its substrate affinity is weaker compared to Arabidopsis enzymes of the ILR1 gene family. Enhanced IAA-hydrolase activity has been observed during clubroot disease in Chinese cabbage. Pssm-ID: 349915 [Multi-domain] Cd Length: 415 Bit Score: 123.58 E-value: 1.53e-31

It is a dimeric zinc-dependent exopeptidase, with two domains, a catalytic domain, which provides the ligands for the two zinc ions in the active site, and a dimerization domain. CPDG2 cleaves the C-terminal glutamate moiety from a wide range of N-acyl groups, including peptidyl, aminoacyl, benzoyl, benzyloxycarbonyl, folyl, and pteroyl groups to release benzoic acid, phenol, and aniline mustards. It is used clinically to treat methotrexate toxicity by hydrolyzing it to inactive and non-toxic metabolites. It is also proposed for use in antibody-directed enzyme prodrug therapy; for example, glutamate can be cleaved from glutamated benzoyl nitrogen mustards, producing nitrogen mustards with effective cytotoxicity against tumor cells.
