蛋白酶的所催化的反应
TEV蛋白酶英语TEV protease的结构,其中红色的为催化三联体

蛋白酶(英語:protease)是生物體內的一類(酵素),它們能夠分解蛋白質。分解方法是打斷那些將氨基酸連結成多肽鏈的肽鍵

蛋白酶是重要的工業酶,佔全球總酶銷售量約六成,其中七成用於工業用途的蛋白酶用於食品發酵等方面[1],例如酸性蛋白酶用於傳統發酵食品和調味品的生產[2][3]催化酪蛋白沈澱;中性蛋白酶因能夠去除水解產物的苦味而令醬油脫苦[4]鹼性蛋白酶應用於食品烘烤等方面[5],因為能夠有效提高生麵團的延性和韌性,並且增強麵包的起泡性。

分類[编辑]

目前已知的蛋白酶可以分成以下六大類:
