L-arabinose metabolism in Herbaspirillum seropedicae.
The pathway for L-arabinose metabolism in Herbaspirillum seropedicae was shown to involve nonphosphorylated intermediates and to produce alpha-ketoglutarate. The activities of the enzymes and the natures of several intermediates were determined. The pathway was inducible by L-arabinose, and two key enzymes, L-arabinose dehydrogenase and 2-keto-glutarate semialdehyde dehydrogenase, were present in all strains of H. seropedicae tested.
