IUBMB Enzyme Nomenclature

EC 1.1.1.358

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 1.1.1.168 2-dehydropantolactone reductase (Re-specific) and EC 1.1.1.214, 2-dehydropantolactone reductase (Si-specific).
