Legumain

Definition:

EC Tree > 3 Hydrolases > 3.4 Acting on peptide bonds (peptidases) > 3.4.22 Cysteine endopeptidases > 3.4.22.34 Legumain
Legumain is an asparaginyl endopeptidase best known from legume seeds, the trematode Schistosoma mansoni and mammalian lysosomes, not inhibited by compound E-64, and the type example of peptidase family C13. It hydrolyzes proteins and small-molecule substrates at -Asn-/-Xaa- bonds, and also acts as a processing enzyme for proproteins and as a ligase in plant seed storage protein maturation. In organisms it contributes to lysosomal proteolysis, antigen processing and seed protein maturation. It features a caspase-like catalytic cysteine-histidine dyad stabilized by an unusual disulfide and pH-dependent zymogen activation.
