into the active-site geometries of both the native and the oxidized enzymes. alpha}-Chymotrypsin with D-isomer selectivity in the hydrolysis of alpha}-methyl-alpha}-nitro esters was used for the synthesis of a D-L pseudopeptide. Molecular modeling together with kinetic results was used to explain the unusual phenomena in hydrolysis and synthesis catalyzed by the native and modifiedenzymes. alpha}-Chymotrypsin
