1.1.3.17 | E312A |
generated for investigation of the negative charge on Glu312, enzyme inactive |
685213 |
1.1.3.17 | E312D |
generated for investigation of the negative charge on Glu312, kcat values about 230times lower and and kcat/Km values about 35times lower than in the wild-type, solvent viscosity and substrate kinetic isotope effects indicates presence of internal equilibrium prior to the hydride transfer reaction |
