KEGG   ENZYME: 3.4.23.41Help
Entry
EC 3.4.23.41                Enzyme                                 

Name
yapsin 1;
yeast aspartic protease 3;
Yap3 gene product (Saccharomyces cerevisiae)
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Aspartic endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Hydrolyses various precursor proteins with Arg or Lys in P1, and commonly Arg or Lys also in P2. The P3 amino acid is usually non-polar, but otherwise additional basic amino acids are favourable in both non-prime and prime positions
Comment
In peptidase family A1 of pepsin, and weakly inhibited by pepstatin. Can partially substitute for kexin in a deficient strain of yeast. The homologous product of the Mkc7 gene (Saccharomyces cerevisiae) has similar catalytic activity and has been termed yapsin 2 [2]
