WebFeb 15, 1998 · Replicative DNA polymerases are highly processive enzymes that polymerize thousands of nucleotides without dissociating from the DNA template. The recently determined structure of the Escherichia coli bacteriophage T7 DNA polymerase suggests a unique mechanism that underlies processivity, and this mechanism may … In molecular biology and biochemistry, processivity is an enzyme's ability to catalyze "consecutive reactions without releasing its substrate". For example, processivity is the average number of nucleotides added by a polymerase enzyme, such as DNA polymerase, per association event with the template strand. … See more Polymerases interact with the phosphate backbone and the minor groove of the DNA, so their interactions do not depend on the specific nucleotide sequence. The binding is largely mediated by electrostatic interactions … See more • • Bedford, E; Tabor, S; Richardson, C. C. (1997).
