DNA phosphorothioation is widespread in many bacterial species. By homology analysis of the dnd gene cluster in Pseudomonas fluorescens Pf0-1, a spfBCDE gene cluster involved in DNA phosphorothioation was localized. Disruption of the spfD gene, a dndD homolog, caused the loss of the Dnd phenotype and demonstrated the involvement of spfD in DNA phosphorothioation in P. fluorescens Pf0-1. The ATPase activity of SpfD suggests that SpfD could hydrolyze ATP to provide the energy required in the DNA phosphorothioate modi. cation process.
