General description
木瓜蛋白酶是一种天然存在于木瓜（Carica papaya L.）中的蛋白水解酶。可以从切开的未成熟木瓜的乳胶中获得。木瓜蛋白酶属于半胱氨酸蛋白酶家族。它是一种球状单链蛋白质，由四个二硫桥和催化基础残基组成。木瓜蛋白酶由全α-结构域和反平行片β-结构域组成。
Application
木瓜蛋白酶被用作嫩肉精。它还被用于在原代细胞培养物制备中分解组织。
Biochem/physiol Actions
木瓜蛋白酶是一种可切割肽键的半胱氨酸蛋白酶，并且已知可切割抗体的Fc部分。
木瓜蛋白酶对许多生物体的生物过程起重要作用。它对蛋白质、氨基酸酯和酰胺连接以及短链肽具有蛋白水解活性。木瓜蛋白酶倾向于切割碱性氨基酸如精氨酸、苯丙氨酸和赖氨酸的肽键。它在药物发现、制药、食品、烘焙和乳制品行业有广泛的应用。
Other Notes
1 U对应于在pH 6.2和25°C下，每分钟水解1 μmol N-苯甲酰基-L-精氨酸乙酯（BAEE，货号 12880）所需的酶量
