Assimilatory nitrate reductase and glutamate dehydrogenase of the red alga Porphyridium aerugineum have been studied. Nitrate reductase exhibits a pH optimum at approx. 7.75; it is functional with reduced benzyl viologen, FMN; FAD, NADH and is not functional with NADPH. In crude extracts of cells grown on nitrate as the sole nitrogen source, a partially inactive form of nitrate reductase occurs. This inactive enzyme can be activated by heating at 50°C. Glutamate dehydrogenase of P. aerugineum is strictly dependent on NADPH. © 1979.

Abstract

Assimilatory nitrate reductase and glutamate dehydrogenase of the red alga Porphyridium aerugineum have been studied. Nitrate reductase exhibits a pH optimum at approx. 7.75; it is functional with reduced benzyl viologen, FMN; FAD, NADH and is not functional with NADPH. In crude extracts of cells grown on nitrate as the sole nitrogen source, a partially inactive form of nitrate reductase occurs. This inactive enzyme can be activated by heating at 50°C. Glutamate dehydrogenase of P. aerugineum is strictly dependent on NADPH. © 1979.
