Crystal Structure of human DNA polymerase lambda in complex with a one nucleotide DNA gap and ddTTP
Overview
Pol lambda is a family X member believed to fill short gaps during DNA, repair. Here we report crystal structures of Pol lambda representing three, steps in filling a single-nucleotide gap. These structures indicate that, unlike other DNA polymerases, Pol lambda does not undergo large subdomain, movements during catalysis, and they provide a clear characterization of, the geometry and stereochemistry of the in-line nucleotidyl transfer, reaction.
About this Structure
1XSN is a Single protein structure of sequence from Homo sapiens with MG, NA, D3T and EDO as ligands. Active as DNA-directed DNA polymerase, with EC number 2.7.7.7 Full crystallographic information is available from OCA.
