THE UNBOUND FORM OF THE INHIBITOR IS GLU-GLY-ARG-CMK-CHLOROMETHYLKETONE. UPON REACTION WITH PROTEIN IT NORMALLY FORMS TWO COVALENT BONDS: 1) A COVALENT BOND TO SER 195 FORMING A HEMIKETAL AR7 AND 2) A COVALENT BOND TO NE2 OF HIS 57. THE GEOMETRY OF THE LIGAND, AS REFINED, HOWEVER DOES NOT SUPPORT SUCH COVALENT BONDING OR HEMIKETAL FORMATION.
