摘要
We demonstrate that the Bacillus subtilis fosB(yndN) gene encodes a fosfomycin resistance protein. Expression of fosB requires sigma (W), and both fosB and sigW mutants are fosfomycin sensitive. FosB is a metallothiol transferase related to the FosA class of Mn2+-dependent glutathione transferases but with a preference for Mg2+ and L-cysteine as cofactors.
