on the basis of the differential sensitivities of e2r to temperature and the inhibition by cibacron blue f3ga of the binding reaction , it is suggested that the polynucleotide-binding domain consists of two types of subsites , one of which has a higher affinity for oligo ( dg ) residues and the other of which recognizes oligo ( dt ) , oligo ( dc ) , and , to a lesser extent , oligo ( da ) .
