Sysname
(S)-2-hydroxypropylphosphonate:hydrogen-peroxide epoxidase
Reaction(IUBMB)
(S)-2-hydroxypropylphosphonate + H2O2 = (1R,2S)-1,2-epoxypropylphosphonate + 2 H2O [RN:R08863]
Reaction(KEGG)
Substrate
(S)-2-hydroxypropylphosphonate [CPD:C06452];
H2O2 [CPD:C00027]
Product
(1R,2S)-1,2-epoxypropylphosphonate;
H2O [CPD:C00001]
Comment
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 [7].
