| PF00082 | Subtilase family (Peptidase_S8) | Subtilase family | Subtilases are a family of serine proteases. They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7 ... | Domain | |
| PF22143 | C5a peptidase, fibronectin type III domain (ScpA_C) | C5a peptidase, fibronectin type III domain | This domain is found at the C-terminal end of C5a peptidase from Streptococcus pyogenes (ScpA) and similar sequences from firmicutes. ScpA is a multidomain cell-envelope subtilase that cleaves complement component C5a. This protein consists of a cata ... | Domain | |
| PF13585 | CHU_C Type IX secretion signal domain (CHU_C) | CHU_C Type IX secretion signal domain | This domain was initially identified from proteins from C. hutchinsonii giving rise to the CHU name. This domain adopts an immunoglobulin like domain that is foundat the C-terminus of various bacterial cell surface proteins. This domain was shown to ... | Domain | |
| PF02225 | PA domain (PA) | PA domain | The PA (Protease associated) domain is found as an insert domain in diverse proteases. The PA domain is also found in a plant vacuolar sorting receptor Swiss:O22925 and members of the RZF family Swiss:O43567. It has been suggested that this domain fo ... | Domain | |
| PF06280 | Fn3-like domain (fn3_5) | Fn3-like domain | Fn3_5 is an fn3-like domain which is frequently found as the first of three on streptococcal C5a peptidase (SCP), a highly specific protease and adhesin/invasin. The family is found in conjunction with Pfam:PF00082, Pfam:PF02225 and Pfam:PF00746 [1]. ... | Domain |
