3hvk Summary


Rat catechol O-methyltransferase in complex with a catechol-type, purine-containing bisubstrate inhibitor - humanized form

The structure was published by Ellermann, M., Jakob-Roetne, R., Lerner, C., et al., Ehler, A., Rudolph, M.G., and Diederich, F., in 2009 in a paper entitled "Molecular recognition at the active site of catechol-o-methyltransferase: energetically favorable replacement of a water molecule imported by a bisubstrate inhibitor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.3 Å and deposited in 2009.

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

The PDB entry contains the structure of Catechol O-methyltransferase. This molecule has the UniProt identifier P22734 (COMT_RAT)search. The sample contained 221 residues which is < 90% of the natural sequence. Out of 221 residues 213 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.
