[Enzymes of carbohydrate metabolism in phototrophic bacteria]
Abstract
Purple sulphur bacteria (Chromatium minutissimum, Ectothiorhodospira shaposhnikovii, Thiocapsa roseopersicina), non-sulphur bacteria (Rhodopseudomonas palustris Rh. viridis), and green sulphur bacteria (Chlorobium limicola f. thiosulfatophillum) contain all enzymes of the fructose diphosphate pathway of carbohydrate transformation, and also glucose-6-phosphate dehydrogenase. The activity of fructose diphosphate aldolase, triose phosphate dehydrogenase, and glucose-6-phosphate dehydrogenase increased in the cultures of Th. roseopersicina and C. limicola f. thiosulfatophillum when they were grown in the presence of glucose. The activity of 6-phosphogluconate dehydrogenase in these bacteria was very low.
