Other name(s): L-arabino-aldose dehydrogenase
Systematic name: L-arabinose:NAD+ 1-oxidoreductase
Comments: The enzymes from the bacterium Azospirillum brasilense and the archaeon Haloferax volcanii are part of the L-arabinose degradation pathway and prefer NADP+ over NAD+. In vitro the enzyme from Azospirillum brasilense shows also high catalytic efficiency with D-galactose.
