L-Arabinose metabolism in Rhizobium japonicum.
l-Arabinose was metabolized through an oxidative pathway by extracts of a strain of Rhizobium japonicum. The findings showed that l-arabinose is converted into 2-keto-3-deoxy-l-arabonate, which is cleaved into glycoaldehyde and pyruvate.
متن کاملL-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 ...
متن کاملA novel alpha-ketoglutaric semialdehyde dehydrogenase: evolutionary insight into an alternative pathway of bacterial L-arabinose metabolism.
Azospirillum brasilense possesses an alternative pathway of l-arabinose metabolism, which is different from the known bacterial and fungal pathways. In a previous paper (Watanabe, S., Kodaki, T., and Makino, K. (2006) J. Biol. Chem. 281, 2612-2623), we identified and characterized l-arabinose 1-dehydrogenase, which catalyzes the first reaction step in this pathway, and we cloned the correspondi...
متن کاملPentose metabolism in Mycobacterium smegmatis: comparison of L-arabinose isomerases induced by L-arabinose and D-galactose.
D-Galactose, which did not serve as a growth substrate, was found to induce an L-arabinose isomerase of similar properties to the L-arabinose-induced L-arabinose isomerase. In both cases the pH profiles, pH stability, optimum temperature, heat stability, substrate specificity, metal ion requirements, mobility on polyacrylamide gel electrophoresis, and kinetic properties of the induced isomerase...
متن کاملNutritional implications of L-arabinose in pigs
The pentose sugar L-arabinose is one of the most abundant components released by complete hydrolysis of non-starch polysaccharides of feed ingredients of vegetable origin. Two studies were conducted to investigate the apparent ileal digestibility and urinary excretion of L-arabinose at dietary inclusion levels of 50 and 100 g/kg, and 25, 50, 75 and 100 g/kg respectively, in pigs. As a reference...
