From a kinetics experiment, the Vmax was determined to be 3200111\4.min-1. For the kinetic assay, 0.2mL, of a 0.05mg/mL solution of enzyme was used, and the enzyme has a molecular weight of 95,000 g/mole.
Assume a reaction volume of 3mL.
Calculate the kcat (in • sec-1) and catalytic efficiency ( in M-1sec-1) for the enzyme.
The Km for the enzyme was determined to be 2.5 x 10-2M.
