Comparison of thermal stabilities of various BCATs. The activity of untreated BCAT enzyme was set at 100%. BCATs were incubated at each temperature for 10 min before measurement. The remaining activities were determined on measuring the temporal decrease of NADH absorbance at 340 nm at 25°C. The activity data of DrBCAT (squares), eBCAT (circles), and HB8BCAT (triangles) are indicated.
