Physiological Direction:
[3C-like proteinase nsp5]
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. 		3.4.22.69 PubMed:12917450, PubMed:14561748
-
[Papain-like protease nsp3]
Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76- residue protein attached to proteins as an intracellular targeting signal). 		3.4.19.12 PubMed:12917450, PubMed:17692280

[RNA-capping enzyme subunit nsp9]
a 5'-end diphospho-ribonucleoside in mRNA + GTP + H(+) = a 5'- end (5'-triphosphoguanosine)-(ribonucleoside) in mRNA + diphosphate 		2.7.7.50 UniProtKB:P0DTC1
