Cytochrome b

Intermolecular
Cysteine 323 and cysteine 45 of Cytochrome b-c1 complex subunit 8
Intramolecular
Cysteine 40 and cysteine 93
A redox-regulated disulphide may form between cysteine 323 of Cytochrome b and cysteine 45 of Cytochrome b-c1 complex subunit 8 (323 and 44 respectively in this structure). However, the redox score of this cysteine pair is lower than any known redox-active intermolecular disulphide. ?
