NMR Structure of the Human Rhinovirus 3C Protease (serotype 14) with covalently bound Ace-LEALFQ-ethylpropionate inhibitor


Function and Biology Details

Reactions catalysed:
NTP + H(2)O = NDP + phosphate. 
Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly. 
Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein. 
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
