C-terminal processing peptidase; serine protease family S41; The C-terminal processing peptidase (CPP, EC 3.4.21.102) also known as tail-specific protease (tsp), the photosystem II D1 C-terminal processing protease (D1P), and other related S41 protease family members are present in this CD. CPP is synthesized as a precursor form with a carboxyl-terminal extension. It specifically recognizes a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. The C-terminal carboxylate group is essential, and proteins where this group is amidated are not substrates. This family of proteases contains the PDZ domain that promotes protein-protein interactions and is important for substrate recognition. The active site consists of a serine/lysine catalytic dyad. The bacterial CCP-1 is believed to be important for the degradation of incorrectly synthesized proteins as well as protection from thermal and osmotic stresses. In E. coli, it is involved in the cleavage of a C-terminal peptide of 11 residues from the precursor form of penicillin-binding protein 3 (PBP3). In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II, allowing the light-driven assembly of the tetranuclear manganese cluster, which is responsible for photosynthetic water oxidation.

C-terminal processing peptidase family S41; Peptidase family S41 (C-terminal processing peptidase or CTPase family) contains very different subfamilies; it includes photosystem II D1 C-terminal processing protease (CTPase), interphotoreceptor retinoid-binding protein IRBP and tricorn protease (TRI). CTPase and TRI both contain the PDZ domain while IRBP, although being very similar to the tail-specific protease domain, lacks the PDZ insertion domain and hydrolytic activity. These serine proteases have distinctly different active sites: in CTPase, the active site consists of a serine/lysine catalytic dyad while in tricorn core protease, it is a tetrad (serine, histidine, serine, glutamate). CPases with different substrate specificities in different species include processing of D1 protein of the photosystem II reaction center in higher plants and cleavage of a peptide of 11 residues from the precursor form of penicillin-binding protein; and others such as tricorn protease (TRI) act as a carboxypeptidase, involved in the degradation of proteasomal products. CTPase homolog IRBP, secreted by photoreceptors into the interphotoreceptor matrix, having arisen in the early evolution of the vertebrate eye, promotes the release of all-trans retinol from photoreceptors and facilitates its delivery to the retinal pigment epithelium.

CPP belongs to the peptidase S41A family. It cleaves a C-terminal 11 residue peptide from the precursor form of penicillin-binding protein 3, and may have a role in protecting bacterium from thermal and osmotic stresses. In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This CPP-like PDZ domain is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus. Pssm-ID: 467623 [Multi-domain] Cd Length: 88 Bit Score: 114.89 E-value: 5.06e-31

Tricorn protease; serine protease family S41; The tricorn protease (TRI), a member of the S41 peptidase family and named for its tricorn-like shape, exists only in some archaea and eubacteria. It has been shown to act as a carboxypeptidase, involved in the degradation of proteasomal products to preferentially yield di- and tripeptides, with subsequent and final degradations to free amino acid residues by tricorn interacting factors, F1, F2 and F3. Tricorn is a hexameric D3-symmetric protease of 720kD, and can self-associate further into a giant icosahedral capsid structure containing twenty copies of the complex. Each tricorn peptidase monomer consists of five structural domains: a six-bladed beta-propeller and a seven-bladed beta-propeller that limit access to the active site, the two domains (C1 and C2) that carry the active site residues, and a PDZ-like domain (proposed to be important for substrate recognition) between the C1 and C2 domains. The active site tetrad residues are distributed between the C1 and C2 domains, with serine and histidine on C1 and serine and glutamate on C2.

Interphotoreceptor retinoid-binding protein; serine protease family S41; Interphotoreceptor retinoid-binding protein (IRBP) is a homolog of the S41 protease, C-terminal processing peptidase (CTPase) family. It is thought to facilitate the compartmentalization of the visual cycle that requires poorly soluble and potentially toxic retinoids to cross the aqueous subretinal space between the photoreceptors and the retinal pigment epithelium (RPE). IRBP is secreted by photoreceptors into the interphotoreceptor matrix (IPM) where it is rapidly turned over by a combination of RPE and photoreceptor endocytosis. It is the most abundant soluble protein component of the IPM, consisting of homologous modules, each repeat structure arising through the duplication (as in teleost IRBP) or quadruplication (in tetrapods) of an ancient gene, arisen in the early evolution of the vertebrate eye. IRBP has been shown to promote the release of all-trans retinol from photoreceptors and facilitates its delivery to the RPE. Conversely, IRBP can promote the release of 11-cis-retinal from the RPE, prevent its isomerization in the subretinal space, and transfer it to photoreceptors. In vivo evidence implicates IRBP as a retinoid transporter in the visual cycle, suggesting a critical role for IRBP in cone function essential for human vision. IRBP is a dominant autoimmune antigen in the eye; IRBP proteolysis analysis has proven a useful biomarker for autoimmune uveitis (AU) disorders, a major cause of blindness. This family also includes a chlamydia-secreted protein, designated chlamydia protease-like activity factor (CPAF), known to degrade host proteins, enabling Chlamydia to evade host defenses and replicate.

CPP is synthesized with an extension on its carboxyl-terminus and specifically recognizes a C-terminal tripeptide, but cleaves at variable distance from the C-terminus. The CPP active site consists of a serine/lysine catalytic dyad. Conservation of these residues is seen in the CPP-like proteins of this group. CPP proteins contain a PDZ domain that promotes protein-protein interactions and is important for substrate recognition however, most of CPP-like proteins only have an internal fragment or lack the PDZ domain.

Typically, these proteases have an N-terminal serine protease domain and at least one C-terminal PDZ domain that recognizes substrates, and in some cases activates the protease function. An exception is yeast Nma11p which has two protease domains and four PDZ domains; its N-terminal half is comprised of a protease domain, followed by two PDZ domains, and its C-terminal half has a similar domain arrangement. HtrA-type proteases include the human HtrA1-4 and MBTPS2, tricorn protease, DegS, DegP and C-terminal processing peptidase, cyanobacterial serine proteases Hhoa, HhoB, and HtrA, and yeast Nma11p. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-termini of their partner proteins (known as PDZ binding motifs).

RseP is involved in the regulation of an extracytoplasmic stress response through the cleavage of membrane-spanning anti-stress-response transcription factor (anti-sigmE) protein RseA; it cleaves the peptide bond between the critical alanine and cysteine in the transmembrane region of RseA, releasing the cytoplasmic domain of RseA with its associated sigmaE. RseP contains two tandem-arranged periplasmic PDZ domains (PDZ-N/PDZ1 and PDZ-C/PDZ2) which act to negatively regulate protease action on intact RseA; they serve as a size-exclusion filter which prevents the access of an intact RseA into the active site of RseP.

DegP belongs to the HtrA family of housekeeping proteases. It acts as a protease, degrading transiently denatured and unfolded or misfolded proteins which accumulate in the periplasm following heat shock or other stress conditions, and as a molecular chaperone at low temperatures. DegP has two PDZ domains in addition to the protease domain; its PDZ1 domain is responsible for identifying the distinct substrate sequences that affect degradation (degron) of the substrate sequence, and its PDZ2 domain is responsible for combining with other DegP monomers to form a stable oligomer structure. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This DegP family PDZ domain 1 is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus. Pssm-ID: 467630 [Multi-domain] Cd Length: 91 Bit Score: 46.71 E-value: 1.14e-06

The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This DegP family PDZ domain 2 is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus. Pssm-ID: 467631 [Multi-domain] Cd Length: 83 Bit Score: 36.45 E-value: 3.43e-03

PDZ domain of PDZ-LIM family proteins, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of PDZ-LIM family proteins including PDLIM1-7, and related domains. PDZ-LIM family proteins (also known as Zasp PDZ domain proteins) are involved in the rearrangement of the actin cytoskeleton; they mediate association with the cytoskeleton through alpha-actinin as well as with other proteins involved in signal transduction pathways. Members of this family include PDLIM1 (also known as C-terminal LIM domain protein 1, elfin, LIM domain protein CLP-36), PDLIM2 (also known as PDZ-LIM protein mystique), PDLIM3 (also known as actinin-associated LIM protein, alpha-actinin-2-associated LIM protein, ALP), PDLIM4 (also known as LIM protein RIL, Reversion-induced LIM protein), PDLIM5 (also known as enigma homolog, ENH, enigma-like PDZ and LIM domains protein), PDLIM6 (also known as LIM domain-binding protein 3, ZASP, Cypher, Oracle), and PDLIM7 (also known as PDZ and LIM domain protein 7, LIM mineralization protein, LMP; protein enigma). PDLIM1 has been shown to negatively regulate NF-kappaB-mediated signaling in the cytoplasm. PDLIM7 negatively regulates p53 through binding murine double minute 2 (MDM2). The PDZ domains of PDZ-LIM family proteins PDLIM1, 2, 3, 5, 6, 7 have been shown to bind actin. Other PDZ-LIM family PDZ domain binding partners include thyroid receptor interacting protein-6 (PDLIM4-PDZ), the LIM domain of PDLIM4 (PDLIM4-PDZ), tropomyosin (PDLIM7-PDZ), myotilin and calsarcin 1 (PDLIM6-PDZ), and proteins from the myotilin and FATZ (calsarcin/myozenin) families (PDLIM1, 3, 4, 6 PDZ domains). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This PDLIM-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

circularly permuted PDZ domain of Bacillus subtilis HtrA-type serine proteases HtrA, HtrB, and YyxA and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Bacillus subtilis HtrA/YkdA, HtrB/YvtA and YyxA/YycK, and related domains. HtrA-type serine proteases participate in folding and degradation of aberrant proteins, and in processing and maturation of native proteins. HtrA, HtrB, and YyxA have a single transmembrane domain at the N-terminus and a PDZ domain at the C-terminus. Expression of htrA and htrB genes is induced both by heat shock and by secretion stress (by a common) mechanism; yyxA is neither heat shock nor secretion stress inducible. HtrA and HtrB may have overlapping cellular functions; YyxA may have a cellular function distinct from the other two proteases or have the same function but under different conditions. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands.

circularly permuted PDZ domain of Synechocystis sp. PCC 6803 putative serine proteases HhoA, HhoB, and HtrA and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of the cyanobacterial Synechocystis sp. PCC 6803 putative serine proteases HhoA, HhoB and HtrA, and related domains. These three proteases are functionally overlapping, and are involved in a number of key physiological responses, ranging from protection against light and heat stresses to phototaxis. HhoA assembles into trimers, mediated by its protease domain and further into a hexamer by a novel interaction between the PDZ domains of opposing trimers. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands.
