应用
Rennin（凝乳酶），也称为 chymosin（凝乳酶），是在小牛胃中产生的乳凝酸蛋白酶。它用于奶酪制作和研究新生儿胃消化。
生化/生理作用
凝乳酶，一条 323 个氨基酸链，分泌时为无活性前体，然后通过限制性蛋白水解转化为活性酶。它能裂解 K-酪蛋白中苯丙氨酸和甲硫氨酸之间的肽键。

Chymosin can specifically break down the Phe105-Met106 peptide bond of milk κ-casein to form insoluble para-κ-casein, resulting in milk coagulation, a process that is used in making cheese. In this study, in order to obtain an alternative milk coagulant which

Chymosin-induced coagulation of individual milk proteins during incubation at 30 °C was investigated using a proteomic approach. The addition of chymosin (0.006 units/mL) caused the milk proteins to coagulate after a 3 h incubation period. Approximately 88% of the milk

The first step in cheesemaking is the milk clotting process, in which κ-caseinolytic enzymes contribute to micelle precipitation. The best enzyme for this purpose is chymosin because of its high degree of specificity toward κ-casein. Although recombinant bovine chymosin is

Epidermal growth factor (EGF) has biological roles, including embryonic organ development, breast morphogenesis, breast cell proliferation, and mammary development. This study aimed to measure EGF concentration and evaluate its relationship with somatic cell count (SCC) in healthy water buffaloes (Bubalus
