+==Crystal Structure of human DNA polymerase lambda in complex with a one nucleotide DNA gap and ddTTP==
-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.

+== Function ==
+[https://www.uniprot.org/uniprot/DPOLL_HUMAN DPOLL_HUMAN] Repair polymerase. Involved in base excision repair (BER) responsible for repair of lesions that give rise to abasic (AP) sites in DNA. Has both DNA polymerase and terminal transferase activities. Has a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity.<ref>PMID:11457865</ref> <ref>PMID:15537631</ref>
