Display the word mapDisplay the reaction diagram Show all sequences 2.7.7.19ATP + RNAn = diphosphate + RNAn+3'-A initial interaction between RNA and the enzyme is characterized by a high enthalpy of association. The minimal RNA binding site of the enzyme is eight nucleotides. Upon RNA binding, the enzyme undergoes structural modifications, although the interaction does not significantly modify the stability of the protein 677275

Display the word mapDisplay the reaction diagram Show all sequences 2.7.7.19ATP + RNAn = diphosphate + RNAn+3'-A non-uniform isomerization of the polymerase-primer complex with time consistent with a discontinuous (saltatory) translocation mechanism. Three distinct translocatory phases can be discerned: a -10(U)-binding site forward movement, a -27/-26(UU)-binding site jump to -10, then a -27/-26(UU)-binding site movement further downstream. Poly(A) tail elongation shows no apparent pauses during these isomerizations 674824
