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
从番木瓜提取的木瓜蛋白酶已用于：
- 酶解大鼠皮质以提取用于细胞培养的星形胶质细胞
- 研究对羊驼精浆粘度和精子功能的影响
- 研究对犀牛精子产量和低温存活率的影响
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。
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。
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

This study aims to understand the enhancing effect of glycosaminoglycans (GAGs), such as chondroitin/dermatan structures, on Fe uptake to Caco-2 cells. High-sulfated GAGs were selectively purified from cooked haddock. An in vitro digestion/Caco-2 cell culture model was used to evaluate

This study continues previous research to confirm that glycosaminoglycans (GAGs) exert a positive effect on promoting iron uptake by Caco-2 cells. Cooked haddock was digested with papain, and GAGs were further purified on the basis of their sulfur content. Reverse
