CRYSTAL STRUCTURE OF A COMPLEX BETWEEN ELECTRON TRANSFER PARTNERS, CYTOCHROME C PEROXIDASE AND CYTOCHROME C

The structure was published by Pelletier, H. and Kraut, J., in 1992 in a paper entitled "Crystal structure of a complex between electron transfer partners, cytochrome c peroxidase and cytochrome c." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1993.

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

This PDB entry contains a complex of 2 biomacromolecules, namely CYTOCHROME C PEROXIDASE and ISO-1-CYTOCHROME C.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
