The two substrates of this enzyme are (R)-pantolactone and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are 2-dehydropantolactone, reduced NADPH, and a proton. [1] [2] [3]

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 (R)-pantolactone:NADP+ oxidoreductase (A-specific). Other names in common use include 2-oxopantoyl lactone reductase, ketopantoyl lactone reductase, 2-ketopantoyl lactone reductase, and 2-dehydropantoyl-lactone reductase (A-specific).
