Crystal Structure of 2,3-dihydroxybiphenyl 1,2-dioxygenase Complexed with 3-methyl Catechol under Anaerobic Condition

The structure was published by Vaillancourt, F.H., Han, S., Fortin, P.D., Bolin, J.T., and Eltis, L.D., in 1998 in a paper entitled "Molecular basis for the stabilization and inhibition of 2, 3-dihydroxybiphenyl 1,2-dioxygenase by t-butanol." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2001.

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

The PDB entry contains the structure of 2,3-DIHYDROXYBIPHENYL 1,2-DIOXYGENASE. This molecule has the UniProt identifier P47228 (BPHC_BURXL)search. The sample contained 297 residues which is 100% of the natural sequence. Out of 297 residues 288 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 most likely forms homooctamers.
