NO COORDINATES ARE INCLUDED FOR RESIDUE 1 OF PTI OR FOR MOST OF RESIDUE 58 OF PTI. IN ORDER NOT TO RESTRAIN THE APPROACH OF OG OF SER B 195 TO THE SUSCEPTIBLE INHIBITOR BOND, THE NORMAL CONSTRAINTS IMPOSED ON THE NON-BONDED INTERACTIONS BETWEEN THIS ATOM AND THE NEIGHBORING ATOMS OF THE INHIBITOR WERE REMOVED BY CONVERTING THIS OG INTO A NEW ATOM TYPE OI WITH NON-BONDING INTERACTION FORCES OF ZERO. THIS ATOM IS IDENTIFIED AS OG IN THE COORDINATES BELOW. | ||||||||||||
