Involved in the arabitol catabolism via the arabitol phosphate route. Catalyzes only the transformation of D-arabitol 1-phosphate (Arb1P) and D-arabitol 5-phosphate (Arb5P) into D-xylulose 5-phosphate (Xlu5P) and ribulose 5-phosphate, respectively. It can use both NAD and NADP. D-arabinitol 1-phosphate + NAD(+) = D-xylulose 5-phosphate + H(+) + NADH Binds 2 manganese ions per subunit. Inhibited by EDTA, 4-hydroxymercuribenzoic acid (PHMB), mercury and zinc ions at a concentration of 2 mM. Optimum pH is 6.8-7.3 in the reductive reaction and pH 8.3-8.6 in the oxidative reaction. Homotetramer. Belongs to the zinc-containing alcohol dehydrogenase family.
