Abstract

This group of serine peptidases belong to the MEROPS peptidase families S8 (subfamilies S8A (subtilisin) and S8B (kexin)) and S53 (sedolisin) both of which are members of clan SB.

The subtilisin family is the second largest serine protease family characterised to date. Over 200 subtilises are presently known, more than 170 of which with their complete amino acid sequence [PubMed9070434]. It is widespread, being found in eubacteria, archaebacteria, eukaryotes and viruses [PubMed7845208]. The vast majority of the family are endopeptidases, although there is an exopeptidase, tripeptidyl peptidase [PubMed7845208, PubMed8439290]. Structures have been determined for several members of the subtilisin family: they exploit the same catalytic triad as the chymotrypsins, although the residues occur in a different order (HDS in chymotrypsin and DHS in subtilisin), but the structures show no other similarity [PubMed7845208, PubMed8439290]. Some subtilisins are mosaic proteins, and others contain N- and C-terminal extensions that show no sequence similarity to any other known protein [PubMed7845208]. Based on sequence homology, a subdivision into six families has been proposed [PubMed9070434].

The proprotein-processing endopeptidases kexin, furin and related enzymes form a distinct subfamily known as the kexin subfamily (S8B). These preferentially cleave C-terminally to paired basic amino acids. Members of this subfamily can be identified by subtly different motifs around the active site [PubMed7845208, PubMed8439290]. Members of the kexin family, along with endopeptidases R, T and K from the yeast Tritirachium and cuticle-degrading peptidase from Metarhizium, require thiol activation. This can be attributed to the presence of Cys-173 near to the active histidine [PubMed8439290].Only 1 viral member of the subtilisin family is known, a 56-kDa protease from herpes virus 1, which infects the channel catfish [PubMed7845208].

Sedolisins (serine-carboxyl peptidases) are proteolytic enzymes whose fold resembles that of subtilisin; however, they are considerably larger, with the mature catalytic domains containing approximately 375 amino acids. The defining features of these enzymes are a unique catalytic triad, Ser-Glu-Asp, as well as the presence of an aspartic acid residue in the oxyanion hole. High-resolution crystal structures have now been solved for sedolisin from Pseudomonas sp. 101, as well as for kumamolisin from a thermophilic bacterium, Bacillus novo sp. MN-32. Mutations in the human gene leads to a fatal neurodegenerative disease [PubMed12673349].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 17 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Subtilisin-like domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 17 hidden Markov models representing the Subtilisin-like superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
