The functional roles of the malate dehydrogenase (MDH) tetrameric and dimeric isoforms in the metabolism of the purple nonsulfur phototrophic bacterium Rhodopseudomonas palustris, strain f-8pt was studied with the use of specific inhibitors. It was shown that the enzyme tetrameric form allows the functioning of the glyoxylate cycle and the dimeric form provides for the operation of the tricarboxylic acid cycle.
