title: Synthesis of arabinitol 1-phosphate and its use for characterization of arabinitol-phosphate dehydrogenase.
abstract: D-arabinitol 1-phosphate (Ara-ol1-P), a substrate for D-arabinitol-phosphate dehydrogenase (APDH), was chemically synthesized from D-arabinonic acid in five steps (O-acetylation, chlorination, reduction, phosphorylation, and de-O-acetylation). Ara-ol1-P was used as a substrate for the characterization of APDH from Bacillus halodurans. APDH converts Ara-ol1-P to xylulose 5-phosphate in the oxidative reaction; both NAD(+) and NADP(+) were accepted as co-factors. Kinetic parameters for the oxidative and reductive reactions are consistent with a ternary complex mechanism.
