(S)-2-hydroxypropylphosphonic acid epoxidase.
based on mapping to UniProt Q56185
(S)-2-hydroxypropylphosphonate + H(2)O(2) = (1R,2S)-1,2- epoxypropylphosphonate + 2 H(2)O.
-!- This is the last enzyme in the biosynthetic pathway of fosfomycin, a broad-spectrum antibiotic produced by certain Streptomyces species. -!- Contains non heme iron that forms a iron(IV)-oxo (ferryl) complex with hydrogen peroxide, which functions as a proton abstractor from the substrate. -!- Formerly EC 1.14.19.7.
