phosphotriesterase and 15 mutant enzymes. For each substrate, the leavinggroup was 4-hydroxyacetophenone while the other two groups attached to the phosphorus core consisted of an asymmetric mixture of methyl, methoxy, ethyl, ethoxy, isopropoxy, phenyl, phenoxy, cyclohexyl, and cyclohexoxy substituents. For the wild-type enzyme, the relative rates of hydrolysis for the two enantiomers ranged from 3 to 5.4 x 10(5)
