Reaction(IUBMB)
TSAVLQ!SGFRK-NH2 and SGVTFQ!GKFKK the two peptides corresponding to the two self-cleavage sites of the SARS 3C-like proteinase are the two most reactive peptide substrates. The enzyme exhibits a strong preference for substrates containing Gln at P1 position and Leu at P2 position.
Comment
SARS coronavirus main protease is the key enzyme in SARS coronavirus replicase polyprotein processing. In peptidase family C30.
