19325183-6	2009	The rate and E(a) of the slow reaction of quinol with oxygen that are observed after cytochrome b is reduced were unaffected by the E272Q substitution, whereas the Y185F mutation modified only its rate.	Oxygen	54-60	cytochrome b	Saccharomyces cerevisiae S288C	85-97	
19478336-5	2009	The rate of superoxide generation by the reconstituted bc(1) complex increased exponentially with increased magnitude of the membrane potential, a finding that is compatible with the suggestion that membrane potential inhibits electron transfer from the cytochrome b(L) to b(H) hemes, thereby promoting the formation of a ubisemiquinone radical that interacts with oxygen to generate superoxide.	Oxygen	365-371	cytochrome b	Saccharomyces cerevisiae S288C	254-266	
20171157-2	2010	The Cytb(558) is the catalytic core of the NADPH-oxidase that generates a superoxide anion from oxygen by using a reducing equivalent provided by NADPH via FAD and two hemes.	Oxygen	96-102	cytochrome b	Saccharomyces cerevisiae S288C	4-8	
6274398-2	1981	The doses required for 50% inhibition were 0.58 mol myxothiazol/mol cytochrome b for oxygen consumption of beef heart mitochondria, and 0.45 mol/mol cytochrome b for NADH oxidation by submitochondrial particles.	Oxygen	85-91	cytochrome b	Saccharomyces cerevisiae S288C	68-80	
19348906-1	2009	Cytochrome b is a pivotal protein subunit of the cytochrome bc(1) complex and forms the ubiquinol oxidation site in the enzyme that is generally thought to be the primary site where electrons are aberrantly diverted from the enzyme, reacting with oxygen to form superoxide anion.	Oxygen	247-253	cytochrome b	Saccharomyces cerevisiae S288C	0-12	
19348906-2	2009	In addition, recent studies have shown that mutations in cytochrome b can substantially increase rates of oxygen radical formation by the bc(1) complex.	Oxygen	106-112	cytochrome b	Saccharomyces cerevisiae S288C	57-69	
19348906-3	2009	It would, thus, be advantageous to be able to manipulate cytochrome b by mutagenesis of the cytochrome b gene to better understand the role of cytochrome b in oxygen radical formation.	Oxygen	159-165	cytochrome b	Saccharomyces cerevisiae S288C	57-69	
19348906-3	2009	It would, thus, be advantageous to be able to manipulate cytochrome b by mutagenesis of the cytochrome b gene to better understand the role of cytochrome b in oxygen radical formation.	Oxygen	159-165	cytochrome b	Saccharomyces cerevisiae S288C	92-104	
19348906-3	2009	It would, thus, be advantageous to be able to manipulate cytochrome b by mutagenesis of the cytochrome b gene to better understand the role of cytochrome b in oxygen radical formation.	Oxygen	159-165	cytochrome b	Saccharomyces cerevisiae S288C	92-104	
235982-17	1975	The kinetics of redox changes in cytochrome b, in the presence of antimycin and oxygen, are distinctly different in the mutant and wild-type particles.	Oxygen	80-86	cytochrome b	Saccharomyces cerevisiae S288C	33-45	
235982-18	1975	They indicate that ubiquinone plays an important role in the phenomenon of the increased reducibility of cytochrome b induced by antimycin plus oxygen.	Oxygen	144-150	cytochrome b	Saccharomyces cerevisiae S288C	105-117
