Name
kumamolysin;
KSCP;
kumamolisin
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Serine endopeptidases
BRITE hierarchy
Reaction(IUBMB)
The enzyme preferentially hydrolyses peptides having an Ala or Pro residue at P2 position and prefers such charged amino acid residues as Glu or Arg at the P2' position. In the oxidized insulin B chain, kumamolysin preferentially cleaves between Leu15 and Tyr16
Comment
This bacterial pepstatin-insensitive carboxyl proteinase has been isolated and characterized from Bacillus sp. MN-32 and from several Burkholderia spp. Kumamolysin from Bacillus sp. MN-32 exhibits a Ser278/Glu78/Asp82 catalytic triad. The enzyme is a type example of peptidase family S53 in the MEROPS Peptidas Database.
