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 18.104.22.168 2-dehydropantolactone reductase (Re-specific) and EC 22.214.171.124, 2-dehydropantolactone reductase (Si-specific).
