The catalytic water was detected
nearby the carbonyl oxygen of the P1 reacting center of the capsid, intNS3, 2A/2B and 4B/5 peptides.
These results led to the order of absolute binding free energy (Gbind) between these substrates and the
NS2B/NS3 protease ranked as capsid > intNS3 > 2A/2B > 4B/5 > 3/4A > 2B/3 in a relative correspondence
with previous experimentally derived values.
