title: Effect of guanosine tetraphosphate on in vitro protein synthesis directed by E1 and E3 colicinogenic factors.
abstract: The in vitro synthesis of colicin E3 was found to be stimulated by guanosine 5'-diphosphate 3'-diphosphate (ppGpp), while that of several other ColE3 plasmid-specific proteins was reduced in the presence of this nucleotide. The ColE1 plasmid-directed in vitro synthesis of colicin E1 was also found to be stimulated by ppGpp.
