+ NADH
 

The two substrates of this enzyme are L-arabinose and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are L-arabino-1,4-lactone, reduced NADH, and a proton. [1] [2]

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-arabinose:NAD+ 1-oxidoreductase. This enzyme participates in ascorbate and aldarate metabolism.
