[https://www.uniprot.org/uniprot/HPPE_STRWE HPPE_STRWE] Non-heme-dependent dioxygenase that catalyzes the oxidative epoxidation of (S)-2-hydroxypropylphosphonate into (1R,2S)-epoxypropylphosphonate, the final step in the biosynthesis of fosfomycin antibiotic.<ref>PMID:16015285</ref> <ref>PMID:16186494</ref>

Hydroxypropylphosphonic acid epoxidase (HppE) is an unusual mononuclear iron enzyme that uses dioxygen to catalyze the oxidative epoxidation of (S)-2-hydroxypropylphosphonic acid (S-HPP) in the biosynthesis of the antibiotic fosfomycin. Additionally, the enzyme converts the R-enantiomer of the substrate (R-HPP) to 2-oxo-propylphosphonic acid. To probe the mechanism of HppE regiospecificity, we determined three X-ray structures: R-HPP with inert cobalt-containing enzyme (Co(II)-HppE) at 2.1 A resolution; R-HPP with active iron-containing enzyme (Fe(II)-HppE) at 3.0 A resolution; and S-HPP-Fe(II)-HppE in complex with dioxygen mimic NO at 2.9 A resolution. These structures, along with previously determined structures of S-HPP-HppE, identify the dioxygen binding site on iron and elegantly illustrate how HppE is able to recognize both substrate enantiomers to catalyze two completely distinct reactions.
