Several microorganisms can utilize l-rhamnose as a carbon and energy source through the nonphosphorylative metabolic pathway, in which l-rhamnose 1-dehydrogenase (RhaDH) catalyzes the NAD(P)+ -dependent oxidization of l-rhamnose to l-rhamnono-1,4-lactone. We herein investigated the crystal structures of RhaDH from Azotobacter vinelandii in ligand-free, NAD+ -bound, NADP+ -bound, and l-rhamnose- and NAD+ -bound forms at 1.9, 2.1, 2.4, and 1.6 Å resolution, respectively. The significant interactions with the 2'-phosphate group of NADP+
