[A comparative study of the isocitrate dehydrogenases of Chlorobium limicola forma Chlorobium thiosulfatophilum and Rhodopseudomonas palustris].
The carboxylation of 2-oxoglutarate in the reductive tricarboxylic acid cycle in the obligate photolithotroph Chlorobium limicola forma thiosulfatophilum and the oxidation of isocitrate in the tricarboxylic acid cycle in the photoheterotroph Rhodopseudomonas palustris are catalyzed by isocitrate dehydrogenases. A comparative study of these enzymes isolated from the two bacteria showed that they virtually do not differ in the enzymatic and kinetic properties.
