WebMay 8, 1991 · In this report, we show that the alpha-like DNA polymerase has an associated 3' to 5'-exonuclease activity which is specific for single-stranded DNA, sensitive to both aphidicolin and N-ethylmaleimide and dependent on high salt concentrations like the polymerase activity. WebTranscription and Gene Regulation. RNA polymerase is the enzyme complex that makes an RNA chain from a double-stranded (or single-stranded) DNA template. RNA polymerase in E. coli is composed of 2 α subunits, 1 β subunit containing the catalytic activity, 1 β’ subunit that has DNA binding activity, and a δ subunit.
