The four substrates of this enzyme are 1-deoxy-11-oxopentalenic acid, reduced nicotinamide adenine dinucleotide phosphate (NADPH), oxygen, and a proton. It products are neopentalenolactone D, oxidised NADP+, and water.[2] The starting ketone is made as part of a biosynthetic pathway in Streptomyces avermitilis which leads to pentalenolactone and related compounds.[1][3]
The enzyme is a Baeyer-Villiger monooxygenase that uses flavin adenine dinucleotide as a cofactor.[1]
