KEGG   ENZYME: 3.4.23.40Help
Entry
EC 3.4.23.40                Enzyme                                 

Name
phytepsin
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Aspartic endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Prefers hydrophobic residues Phe, Val, Ile, Leu, and Ala at P1 and P1', but also cleaves -Phe!Asp- and -Asp!Asp- bonds in 2S albumin from plant seeds
Comment
Known particularly from barley grain, but present in other plants also. In peptidase family A1 (pepsin A family), but structurally distinct in containing an internal region of about 100 amino acids not generally present in the family
History
