Accepted name: 2-dehydropantolactone reductase
Reaction: (R)-pantolactone + NADP+ = 2-dehydropantolactone + NADPH + H+
Other name(s): 2-oxopantoyl lactone reductase; 2-ketopantoyl lactone reductase; ketopantoyl lactone reductase; 2-dehydropantoyl-lactone reductase
Systematic name: (R)-pantolactone:NADP+ oxidoreductase
Comments: The enzyme participates in an alternative pathway for biosynthesis of (R)-pantothenate (vitamin B5). This entry covers enzymes whose stereo specificity for NADP+ is not known. cf. EC 2-dehydropantolactone reductase (Re-specific) and EC, 2-dehydropantolactone reductase (Si-specific).
