3a42 Summary


Crystal structure of MvNei1

The structure was published by Imamura, K., Wallace, S.S., and Doublie, S., in 2009 in a paper entitled "Structural Characterization of a Viral NEIL1 Ortholog Unliganded and Bound to Abasic Site-containing DNA" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2009.

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

The PDB entry contains the structure of Formamidopyrimidine-DNA glycosylase. This molecule has the UniProt identifier Q5UQ00 (FPG_MIMIV)search. The sample contained 295 residues which is 100% of the natural sequence. Out of 295 residues 282 were observed and are deposited in the PDB.

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 is most likely monomeric.
