Conversion of 2HP in Rhodococcus erythropolis SQ1 transformed with recombinant plasmids, each carrying a different combination of genes from the hpo locus. (A) R. erythropolis SQ1 (control without plasmids); (B) R. erythropolis SQ1 harboring the pHpoBCDEFG plasmid; (C) R. erythropolis SQ1 transformed with pHpoBCDEFG and pNitHpoH. For HPLC-MS analysis, cultures of Rhodococcus erythropolis SQ1 were incubated in potassium phosphate buffer supplemented with 0.2 mM 2HP for 2 h. The total-ion chromatograms (TIC) were recorded in the positive-ion (E+) or negative-ion (E−) mode from the MS.
