1eh6 Summary



The structure was published by Daniels, D.S., Mol, C.D., Arvai, A.S., Kanugula, S., Pegg, A.E., and Tainer, J.A., in 2000 in a paper entitled "Active and alkylated human AGT structures: a novel zinc site, inhibitor and extrahelical base binding." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2000.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of O6-ALKYLGUANINE-DNA ALKYLTRANSFERASE. This molecule has the UniProt identifier P16455 (MGMT_HUMAN)search. The sample contained 207 residues which is 100% of the natural sequence. Out of 207 residues 168 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.
