Rennin
Definition:
(n.) A milk-clotting enzyme obtained from the true stomach (abomasum) of a suckling calf. Mol. wt. about 31,000. Also called chymosin, rennase, and abomasal enzyme.
Example Sentences:

(2) Mucor rennin was efficiently excreted from the yeast host as a heavily glycosylated form.
(3) One-day-old rats have a protease with a pH optimum of 3.8 to 4.2 similar to that of calf rennin.
(4) Another expression system for production of Mucor rennin in Saccharomyces cerevisiae was also established.
(5) The greatest differences between experimental and control cheeses (produced with rennin) in the contents of the above-mentioned constituents were observed within the first 30 days.
(6) The lactogenic response of mouse mammary gland explants to human placental lactogen (hPL) and ovine pituitary prolactin (oPRL) was examined on days 10 to 18 of pregnancy by measuring 3H-amino acid incorporation into calcium-rennin precipitable casein.
