H61M mutant of flavocytochrome c3

The structure was published by Rothery, E.L., Mowat, C.G., Miles, C.S., Walkinshaw, M.D., Reid, G.A., and Chapman, S.K., in 2003 in a paper entitled "Histidine 61: An Important Heme Ligand in the Soluble Fumarate Reductase from Shewanella frigidimarina" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2003.

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

The PDB entry contains the structure of flavocytochrome c3. This molecule has the UniProt identifier P0C278 (FRDA_SHEFR)search. The sample contained 571 residues which is 100% of the natural sequence. Out of 571 residues 563 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.
