The catalytic triad chymotrypsin consists of an aspartic acidresidue, a histidine residue, and a serine residue. Drawthese residues in the form, charge, and alignment that they wouldbe in at the active site at pH 7. Indicate clearly how theyare aligned to each other, in order fro them to most efficientlycarry out their combined catalysis. Dont' draw in substrate that isbeing attacked.
