WebA cathepsin is a type of protease, ie a type of protein that breaks apart other proteins. Cathepsins are present in all types of cells, from hepatocytes to neurons, and in many species including all animals. Cathepsin actually refers to a family of proteases. WebNov 16, 2024 · The COVID M pro (main protease) is a cysteine protease inhibitor, meaning that it uses the thiol (S-H) group on the amino acid cysteine to catalyze the cleavage of the protein's amide bond. Paxlovid is designed to inhibit this process by reacting with the carbon designated with a green star (below). What's going on here is not as bad …
http://pfam-legacy.xfam.org/family/Peptidase_C1 Cysteine is a semiessential proteinogenic amino acid with the formula HOOC−CH(−NH2)−CH2−SH. The thiol side chain in cysteine often participates in enzymatic reactions as a nucleophile. Cysteine is chiral. Only L-cysteine is found in nature. The thiol is susceptible to oxidation to give the disulfide derivative cystine, whic…
Cysteine proteases, also known as thiol proteases, are hydrolase enzymes that degrade proteins.
