Mannan-binding lectin-associated serine protease-2 (EC 3.4.21.104, MASP-2, MASP2, MBP-associated serine protease-2, mannose-binding lectin-associated serine protease-2, p100, mannan-binding lectin-associated serine peptidase 2) is an enzyme.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction
- Selective cleavage after Arg223 in complement component C2 (-Ser-Leu-Gly-Arg-Lys-Ile-Gln-Ile) and after Arg76 in complement component C4 (-Gly-Leu-Gln-Arg-Ala-Leu-Glu-Ile)
This mannan-binding lectin (MBL) recognizes patterns of neutral carbohydrates, such as mannose and N-acetylglucosamine.
