L-arabinose + NAD+ the enzyme catalyzes the oxidation of L-arabinose with both NADP+ and NAD+ as electron acceptor, with a slight preference for NADP+. The enzyme is highly specific for L-arabinose as substrate. D-Ribose, D-glucose, D-talose, D-galactose, D-arabinose, D-xylose, D-mannose, L-mannose and D-fructose are not used at significant rates, measured with both NADP+ and NAD+, respectively, as electron acceptors Haloferax volcanii L-arabinono-1,4-lactone + NADH + H+

General Information

General Information Comment Organism
malfunction the L-AraDH deletion mutant does not grow on L-arabinose, whereas growth on D-xylose and glucose is unaffected Haloferax volcanii
physiological function the enzyme is functionally involved in L-arabinose catabolism but not in D-xylose degradation Haloferax volcanii
