periplasmic serine protease, Do/DeqQ family; This family consists of a set proteins various designated DegP, heat shock protein HtrA, and protease DO. The ortholog in Pseudomonas aeruginosa is designated MucD and is found in an operon that controls mucoid phenotype. This family also includes the DegQ (HhoA) paralog in E. coli which can rescue a DegP mutant, but not the smaller DegS paralog, which cannot. Members of this family are located in the periplasm and have separable functions as both protease and chaperone. Members have a trypsin domain and two copies of a PDZ domain. This protein protects bacteria from thermal and other stresses and may be important for the survival of bacterial pathogens.// The chaperone function is dominant at low temperatures, whereas the proteolytic activity is turned on at elevated temperatures.

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. 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.

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.

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).

YlbL is an S16 protease which participates with another unrelated S41 protease (CtpA) in a dual protease mechanism that promotes DNA damage checkpoint recovery. Deletion of both proteases leads to accumulation of the cell division inhibitor YneA.

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. PDZ domains usually bind in 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.

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.

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: 39.39 E-value: 3.55e-04

Domain present in PSD-95, Dlg, and ZO-1/2; Also called DHR (Dlg homologous region) or GLGF (relatively well conserved tetrapeptide in these domains). Some PDZs have been shown to bind C-terminal polypeptides; others appear to bind internal (non-C-terminal) polypeptides. Different PDZs possess different binding specificities.

circularly permuted PDZ domain of DegS serine endoprotease; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Escherichia coli DegS and related domains. DegS (also known as Site-1 protease DegS, S1P protease DegS, and Site-1-type intramembrane protease) participates in the activation of the sigma(E) extracytoplasmic stress response. Initially, there is an accumulation of misfolded membrane proteins (OMPs) in the periplasm which bind by their YXF motif to the DegS PDZ domain, activating DegS-catalyzed cleavage of the RseA periplasmic domain and making RseA a substrate for cleavage by another membrane protease RseP. 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 DegS family 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: 467620 [Multi-domain] Cd Length: 93 Bit Score: 36.99 E-value: 2.51e-03

circularly permuted PDZ domain of high-temperature requirement factor A (HtrA) family serine proteases and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of HtrA family serine proteases including human HtrA1, HtrA2 (mitochondrial), HtrA3, and HtrA4, and related domains. These proteases are key enzymes associated with pregnancy. Their diverse biological functions include cell growth proliferation, migration and apoptosis. They are also implicated in disorders including Alzheimer's, Parkinson's, arthritis and cancer. HtrA1 (also known as high-temperature requirement A serine peptidase 1, L56, and serine protease 11) substrates include extracellular matrix proteins, proteoglycans, and insulin-like growth factor (IGF)-binding proteins. HtrA1 also inhibits signaling by members of the transforming growth factor beta (TGF-beta) family.
