Structure of DNA Polymerase I Klenow Fragment Bound to Duplex DNA

Beese, Lorena S., Derbyshire, Victoria, Steitz, Thomas A.·1993·Science

Abstract

Klenow fragment of Escherichia coli DNA polymerase I, which was cocrystallized with duplex DNA, positioned 11 base pairs of DNA in a groove that lies at right angles to the cleft that contains the polymerase active site and is adjacent to the 3′ to 5′ exonuclease domain. When the fragment bound DNA, a region previously referred to as the "disordered domain" became more ordered and moved along with two helices toward the 3′ to 5′ exonuclease domain to form the binding groove. A single-stranded, 3′ extension of three nucleotides bound to the 3′ to 5′ exonuclease active site. Although this cocrystal structure appears to be an editing complex, it suggests that the primer strand approaches the catalytic site of the polymerase from the direction of the 3′ to 5′ exonuclease domain and that the duplex DNA product may bend to enter the cleft that contains the polymerase catalytic site.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
