Subunit complex III-IV as the nucleotide binding site of Qβ replicase

Abstract

OF the four subunits of Qβ replicase, I, III and IV are bacterial proteins and II is coded for by the phage genome1,2. Among host-derived subunits, I is identified as factor i, a protein which controls cistron-specific translation in Escherichia coli3,4, and III and IV are identified as protein synthesis elongation factors, EFTu and EFTs (ref. 5), respectively.
