β¦ Synopsis
Specific messenger RNA for glutamate dehydrogenase was partially purified from a calf liver polysomal poly(A)-mRNA fraction by sucrose density gradient centrifugation. Enzyme activity in the translational incubation mixture was detected by measuring NADH oxidation in the presence of c~-ketoglutarate and ammonia as a decrease in absorbancy 340-442 nm in a dual wavelength Aminco DW-2 spectrophotometer.

A new spectrophotometric procedure is described for determining glutamate-dependent activities of aspartate aminotransferase, alanine aminotransferase, and ornithine aminotransferase with NADPH-linked glutamate dehydrogenase (GDH) from nitrate-grown Stichococcus bacillaris. The algal NADPH-GDH is hi
