2.7.2.4. Glutamate dehydrogenase (NADH-GDH; EC 1.4.1.2) activity
Glutamate dehydrogenase activity (aminating) was determined spectrophotometrically at 340 nm by measuring oxidation of NADH by the method of Chávez and Candau (1991). One unit (U) GDH activity is defined as 1 nmol NADH oxidized min–1.
