'''T7 DNA POLYMERASE COMPLEXED TO DNA PRIMER/TEMPLATE,A NUCLEOSIDE TRIPHOSPHATE, AND ITS PROCESSIVITY FACTOR THIOREDOXIN'''
===T7 DNA POLYMERASE COMPLEXED TO DNA PRIMER/TEMPLATE,A NUCLEOSIDE TRIPHOSPHATE, AND ITS PROCESSIVITY FACTOR THIOREDOXIN===




==Overview==
<!--
DNA polymerases change their specificity for nucleotide substrates with each catalytic cycle, while achieving error frequencies in the range of 10(-5) to 10(-6). Here we present a 2.2 A crystal structure of the replicative DNA polymerase from bacteriophage T7 complexed with a primer-template and a nucleoside triphosphate in the polymerase active site. The structure illustrates how nucleotides are selected in a template-directed manner, and provides a structural basis for a metal-assisted mechanism of phosphoryl transfer by a large group of related polymerases.
The line below this paragraph, {{ABSTRACT_PUBMED_9440688}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 9440688 is the PubMed ID number.
