Genome Property Definition Page

Accession	GenProp0618
Name	cytochrome (quinone) oxidase, bo type
Type	SYSTEM
Description	The cytochrome bo complex is a quinol oxidase, oxygen reductase which functions in electron transfer chain of aerobic respiration in bacteria. The bo complex contains two heme b (protoheme IX) molecules designated b562 and b595 as well as an active site copper atom. This complex is structurally analagous to the aa3-type cytochrome c oxidases [1] which contains cytochromes a and copper.
JCVI Role	Electron transport
Parent Property	GenProp0616: single complex oxygen reduction and quinone re-oxidation
Literature References	[ 1 ]Chepuri V, Lemieux L, Au DC, Gennis RB  The sequence of the cyo operon indicates substantial structural similarities between the cytochrome o ubiquinol oxidase of Escherichia coli and the aa3-type family of cytochrome c oxidases.  J Biol Chem. 1990 Jul 5;265(19):11185-92.  PMID 2162835
