EC 1.1.1.376 Details
EC number
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
Comment
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].
