Human TDG N140A mutant IN A COMPLEX WITH 5-carboxylcytosine (5caC)

The structure was published by Hashimoto, H., Zhang, X., and Cheng, X., in 2013 in a paper entitled "Activity and crystal structure of human thymine DNA glycosylase mutant N140A with 5-carboxylcytosine DNA at low pH." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.582 Å and deposited in 2013.

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

This PDB entry contains a complex of 3 biomacromolecules, namely G/T mismatch-specific thymine DNA glycosylase, oligonucleotide, and oligonucleotide containing 5-carboxylcytosine.

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.
