  • Aminolevulinic acid(ALA) was shown to be synthesized via active pathways of either C4 or C5 ALA biosynthesis in cells of a photosynthetic bacterium, Rhodocyclus gelatinosus KUP-74, where the C5 pathway was appeared to be preferntially expressed in the cells. It was strongly suggested that L-glutamine might be utilized more effectively than L-glutamate to synthesize ALA via C5 pathway in this bacterium from the fact of relationship between the cellular uptake rates of glutamate and its Gamma-derivaties and corresponded ALA productivities in vitro and in vivo.
