3vta

Reaction: Hydrolysis of proteins with broad specificity.
Comments: From the sarcocarp of the musk melon (Cucumis melo). Other endopeptidases from plants, which are less well characterized but presumably of serine-type, include euphorbain from Euphorbia cerifera, solanain from horse-nettle Solanum elaeagnifolium, hurain from Hura crepitans and tabernamontanain from Tabernamontana grandiflora. Belongs to peptidase family S8.
