title: Characterization of a soluble NADH-independent nitrate reductase from the photosynthetic bacterium Rhodopseudomonas capsulata.
abstract: The assimilatory nitrate reductase was purified 60-fold from a newly isolated, nitrate assmilating strain of the photosynthetic bacterium Rhodopseudomonas capsulata. The enzyme had a molecular weight of about 180 000 dalton and was typically prokaryotic in that it was not active with reduced pyridine nucleotides but rather with reduced flavins.
