Complex between the Lactococcus lactis Fpg and an abasic site containing DNA.

The structure was published by Pereira de Jesus, K., Serre, L., Zelwer, C., and Castaing, B., in 2005 in a paper entitled "Structural insights into abasic site for Fpg specific binding and catalysis: comparative high-resolution crystallographic studies of Fpg bound to various models of abasic site analogues-containing DNA." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely DNA (5'-D(*CP*TP*CP*TP*TP*TP*(3DR)P*TP*TP*TP*CP*TP*CP*G)-3'), DNA (5'-D(*GP*CP*GP*AP*GP*AP*AP*AP*CP*AP*AP*AP*GP*A)-3'), and Formamidopyrimidine-DNA glycosylase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
