EC 1.1.1.376

Accepted name: L-arabinose 1-dehydrogenase [NAD(P)+]

Reaction: α-L-arabinopyranose + NAD(P)+ = L-arabinono-1,4-lactone + NAD(P)H + H+

Other name(s): L-arabino-aldose dehydrogenase

Systematic name: α-L-arabinopyranose:NAD(P)+ 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. The enzyme is specific for α-L-arabinopyranose [3,4].
