CC -!- FUNCTION: Non-heme-dependent dioxygenase that catalyzes the oxidative
CC epoxidation of (S)-2-hydroxypropylphosphonate into (1R,2S)-
CC epoxypropylphosphonate, the final step in the biosynthesis of
CC fosfomycin antibiotic. {ECO:0000269|PubMed:18656958}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-2-hydroxypropylphosphonate + H2O2 = (1R,2S)-
CC epoxypropylphosphonate + 2 H2O; Xref=Rhea:RHEA:10808,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:16240, ChEBI:CHEBI:62246,

CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000269|PubMed:18656958};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000269|PubMed:18656958};
CC -!- PATHWAY: Antibiotic biosynthesis; fosfomycin biosynthesis.
CC {ECO:0000305|PubMed:18656958}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000305|PubMed:18656958}.
CC -!- SIMILARITY: Belongs to the non-heme iron-dependent dioxygenase family.
CC {ECO:0000305}.
