Type: | Family | Name: | Peptidase C13, legumain |
Description: | Asparaginyl endopeptidase, also known as legumain, is a family of cysteine proteases found in many organisms. This group of cysteine peptidases belong to the MEROPS peptidase family C13 (legumain family, clan CD). A type example is legumain from Canavalia ensiformis(Jack bean, Horse bean) []. Although legumains were first described from beans (also known as Vacuolar Processing Enzymes), homologues have been identified in plants, protozoa, vertebrates, and helminths [, ]. In blood-feeding helminths, asparaginyl endopeptidases (sometimes described as hemoglobinases) have been located in the gut and are considered to be involved in host hemoglobin digestion [, , , ].Also included in the family C13 of cysteine peptidases are GPI-anchor transamidases, which share significant homology with legumains. GPI-anchor transamidases mediate glycosylphosphatidylinositol (GPI) anchoring in the endoplasmic reticulum [, ]. | Short Name: | Peptidase_C13 |
