WebN2 - In the crystal structure of uncomplexed native chymosin, the beta-hairpin at the active site, known as 'the flap', adopts a different conformation from that of other aspartic proteinases. This conformation would prevent the mode of binding of substrates/inhibitors generally found in other aspartic proteinase complexes. WebThe effect of milk-clotting enzymes (MCEs) of animal origin (Naturen Extra with a mass fraction of chymosins of 95%, “Bovine Pepsin” with a mass fraction of chymosin of 10%), as well as MCEs of microbial origin (Fromase 750 XLG) and recombinant origin (Chy-max Extra and Chy-max Supreme) on the duration of milk coagulation and processing of ...
WebTwo aspartates in the center of the cleft, Asp32 and Asp215, function as catalytic residues, and thus pepsinogens are classified as aspartic proteinases. Conversion of pepsinogens to pepsins proceeds autocatalytically at acidic pH by two different pathways, a one-step pathway to release the intact activation segment directly, and a stepwise ...

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. It is widely used in the production of cheese.
