蛋白酶解 Proteolysis

(重定向自Proteolytic)
蛋白酶体的结构:其降解蛋白质的反应活性中心位于内部(蓝色)
The hydrolysis of a protein (red) by the nucleophilic attack of water (blue). The uncatalysed half-life is several hundred years.

蛋白酶解蛋白水解英语:Proteolysis)是指蛋白质降解为较小的多肽或氨基酸的过程。通常情况下,被水解的都是肽键,且在蛋白酶的作用下进行,因此常用蛋白酶解。但也可能发生分子内消化,以及不依赖酶的途径,如酸和热的作用而产生的降解。

蛋白酶解在有机体中有多种用途,比如消化酶降解食物中的蛋白,为机体提供氨基酸;完成翻译的多肽链也需要水解加工才能产生有活性的蛋白质;某些生理和细胞过程的调控也是通过蛋白质的酶解进行;还有蛋白酶解可以防止不必要的或不正常的蛋白质在细胞中的积累。

Proteolysis 蛋白酶解

(重定向自Proteolytic)
The hydrolysis of a protein (red) by the nucleophilic attack of water (blue). The uncatalysed half-life is several hundred years.
Structure of a proteasome. Its active sites are inside the tube (blue) where proteins are degraded.

Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. Uncatalysed, the hydrolysis of peptide bonds is extremely slow, taking hundreds of years. Proteolysis is typically catalysed by cellular enzymes called proteases, but may also occur by intra-molecular digestion. Low pH or high temperatures can also cause proteolysis non-enzymatically.
