2nwf Summary


Soluble domain of Rieske Iron Sulfur Protein

The structure was published by Kolling, D.J., Brunzelle, J.S., Lhee, S., Crofts, A.R., and Nair, S.K., in 2007 in a paper entitled "Atomic resolution structures of rieske iron-sulfur protein: role of hydrogen bonds in tuning the redox potential of iron-sulfur clusters." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.1 Å and deposited in 2006.

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

The PDB entry contains the structure of Ubiquinol-cytochrome c reductase iron-sulfur subunit. This molecule has the UniProt identifier Q02762 (UCRI_RHOSH)search. The sample contained 141 residues which is < 90% of the natural sequence. Out of 141 residues 140 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.
