Determinants of acp transferase activity in E. coli YfiP. (A) Truncated or point mutated YfiP variants were expressed in E. coli ΔyfiP cells, and the degree of acp3U-47 modification of tRNAArg-ICG was analyzed by primer extension in comparison to the wild type (wt) and ΔyfiP cells with the empty vector (vc). (B) As shown by primer extension analysis, the YfiP homolog from Variovorax paradoxum (Vp), but not from Clostridium saccharoperbutylacetonicum (Cs), is functional as an acp3U-47 transferase in E. coli ΔyfiP.
