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。应用:
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。
Papain is a proteolytic enzyme and is naturally occurring in papaya (Carica papaya L.). It is obtained from the latex of cut unripe papaya. Papain belongs to the cysteine proteinase family. It is a globular, single-chain protein composed of four disulfide bridges and catalytically essential residues. Papain consists of an all α-domain and anti-parallel β-sheet domain.
Application:
Papain from
Carica papaya has been used:
- in the enzymatic dissociation of rat cortices to extract astrocytes for cell culture
- to study its effects on Alpaca seminal plasma viscosity and sperm function
- to study its effects on the yield and cryo-survival of Rhinoceros spermatozoa
Papain is used as a meat tenderizer. It′s also used to break up tissue in the preparation of primary cell cultures.
