The enzyme, which occurs in the bacteria Azotobacter vinelandii and Sphingomonas sp. SKA58, is part of the non-phosphorylative degradation pathway for L-rhamnose. The enzyme differs in cofactor specificity from EC 220.127.116.11, L-rhamnose 1-dehydrogenase, which is specific for NAD+ and EC 18.104.22.1687, L-rhamnose 1-dehydrogenase (NADP+).
