Method: X-ray diffraction, Resolution 2.208Å Ligands: ARA, NAP Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function ARAA_AZOBR Catalyzes the NAD(P)(+)-dependent conversion of L-arabinose to L-arabino-gamma-lactone. Is involved in a degradation pathway of L-arabinose that allows A.brasilense to grow on L-arabinose as a sole carbon source. Prefers NADP(+) to NAD(+) as electron acceptor. Displays high catalytic efficiency for both L-arabinose and D-galactose in vitro. However, the enzyme appears to be involved in the metabolism of L-arabinose but not D-galactose in vivo. To a lesser extent, is also active on D-talose and D-xylose as substrates in vitro, but not with D-arabinose, D-glucose, D-ribose, L-xylose, L-mannose, L-lyxose, and D-fructose.
