D-arabinose 1-dehydrogenase (ARA2) and similar proteins
ARA2 (EC1.1.1.116), also called NAD(+)-specific D-arabinose dehydrogenase, catalyzes the the oxidation of D-arabinose to D-arabinono-1,4-lactone in the presence of NAD(+).
Comment:Based on the structure evidence that Rattus norvegicus voltage-dependent K+ channel beta subunit (3EAU) in complex with cortisone and cofactor NADPH.
