Thus, the two substrates of this enzyme are L-rhamnofuranose and NAD+, whereas its 3 products are L-rhamno-1,4-lactone, NADH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-rhamnofuranose:NAD+ 1-oxidoreductase. This enzyme participates in fructose and mannose metabolism.
