Accepted name: (4-alkanoyl-5-oxo-2,5-dihydrofuran-3-yl)methyl phosphate reductase

Reaction: a [(3S,4R)-4-alkanoyl-5-oxooxolan-3-yl]methyl phosphate + NADP+ = a (4-alkanoyl-5-oxo-2,5-dihydrofuran-3-yl)methyl phosphate + NADPH + H+

Other name(s): bprA (gene name); scbC (gene name)

Systematic name: [(3S,4R)-4-alkanoyl-5-oxooxolan-3-yl]methyl-phosphate:NADP+ oxidoreductase

Comments: The enzyme, characterized from the bacteria Streptomyces griseus and Streptomyces coelicolor, is involved in the biosynthesis of γ-butyrolactone autoregulators that control secondary metabolism and morphological development in Streptomyces bacteria.
