|
|
|
|
|
|
||
| UniProt code: Q3J5G0. |
|
||
| Organism: | |
Rhodobacter sphaeroides (strain ATCC 17023 / DSM 158 / JCM 6121 / NBRC 12203 / NCIMB 8253 / ATH 2.4.1.) (Cereibacter sphaeroides). |
| Taxonomy: | |
Bacteria; Proteobacteria; Alphaproteobacteria; Rhodobacterales; Rhodobacteraceae; Luteovulum. |
|
||
|
||
| Function: | |
Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B). {ECO:0000256|RuleBase:RU004024}. |
|
||
| Catalytic activity: | |
Reaction=4 [Fe(II)cytochrome c] + 4 H(+) + O2 = 4 [Fe(III)cytochrome c] + 2 H2O; Xref=Rhea:RHEA:11436, Rhea:RHEA-COMP:10350, Rhea:RHEA- COMP:14399, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:29033, ChEBI:CHEBI:29034; EC=7.1.1.9; Evidence={ECO:0000256|ARBA:ARBA00000342, ECO:0000256|RuleBase:RU004024}; |
