YEAST CYTOCHROME BC1 COMPLEX WITH BOUND SUBSTRATE CYTOCHROME C

The structure was published by Lange, C. and Hunte, C., in 2002 in a paper entitled "Crystal structure of the yeast cytochrome bc1 complex with its bound substrate cytochrome c." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.97 Å and deposited in 2002.

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

This entry contains 34 copies of 12 unique biopolymers (complete list).

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 most likely quaternary structure is a 23meric assembly.
