ENTRY EC 3.4.21.25
NAME Cucumisin
CLASS Hydrolases
Acting on peptide bonds (peptidases)
Serine endopeptidases
REACTION Hydrolysis of proteins with broad specificity
SUBSTRATE Peptide
H2O
PRODUCT Peptide
COMMENT From the sarcocarp of the musk melon (Cucumis melo). A homologue
of subtilisin. Other endopeptidases from plants, which are less
well characterized but presumably of serine-type, include
euphorbain from Euphorbia cerifera (formerly EC 3.4.21.56),
solanain from horse-nettle Solanum elaegnifolium (formerly
EC 3.4.99.21), hurain from Hura crepitans (formerly EC 3.4.99.9)
and tavernamontanain from Tabernamontana grandiflora
(formerly EC 3.4.99.23).
