Chymosin / ˈkaɪməsɪn / or rennin / ˈrɛnɪn / is a protease found in rennet. It is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption.

Chymosin (rennin; EC 3.4.23.4) is a neonatal gastric aspartic proteinase and is of commercial importance in cheese-making. It belongs to the aspartic proteinase family which is widely distributed in many organisms and tissues with different physiological and functional properties.

Mar 4, 2023 · Chymosin, a similar enzyme from the fourth stomach of the calf, is responsible for clotting milk when the young animal suckles from its mother. This helps retain the semisolid form of milk proteins in the digestive track for further processing.

Chymosin is an enzyme, found in calf rennet, that plays a crucial role in cheese production by causing milk to clot through the splitting of κ-casein, leading to the formation of a gel structure essential for cheese-making.

Chymosin, known also as rennin, is a proteolytic enzyme related to pepsin that synthesized by chief cells in the stomach of some animals. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal.

Feb 16, 2024 · Chymosin, or rennin, is an enzyme of the hydrolase class (and of the A1 peptidase family), necessary for the digestion of casein present in milk. Chymosin is produced, together with pepsinogen, by adelomorphic (or zymogenic) cells at the level of …

Bovine and camel chymosin are aspartic peptidases that are used industrially in cheese production. They cleave the Phe105-Met106 bond of the milk protein κ-casein, releasing its predominantly negatively charged C-terminus, which leads …

Jul 7, 2024 · Chymosin, an aspartic protease present in the stomachs of young ruminants like cows (bovine), causes milk coagulation and cheese production through the breakdown of κ-casein peptide bonds at the Met105-Phe106 site.

Aug 22, 2018 · Rennin (chymosin) is an enzyme found in the stomach of young mammals, and it is also the active ingredient in the rennet, traditionally used in cheesemaking processes. However, today rennet is used to describe any type of enzyme …

Chymosin was the first registered food enzyme produced commercially using recombinant DNA technology. It plays an important role in texture and flavor formation in cheese besides its renneting activity.
