10531315-1	1999	We have examined the pre-steady state reduction kinetics of the Saccharomyces cerevisiae cytochrome bc(1) complex by menaquinol in the presence and absence of endogenous ubiquinone to elucidate the mechanism of triphasic cytochrome b reduction.	menaquinol	117-127	cytochrome b	Saccharomyces cerevisiae S288C	89-101	
10531315-4	1999	With cytochrome bc(1) complex from a yeast mutant that cannot synthesize ubiquinone, cytochrome b reduction by either menaquinol or ubiquinol was rapid and monophasic.	menaquinol	118-128	cytochrome b	Saccharomyces cerevisiae S288C	5-17	
15833742-3	2005	The extent of cytochrome b reduction by variable concentrations of menaquinol could only be fitted to a kinetic model that assumes electron equilibration between center N sites in the dimer.	menaquinol	67-77	cytochrome b	Saccharomyces cerevisiae S288C	14-26	
12377760-4	2002	Although the bc(1) complex lacking the Rieske iron-sulfur cluster cannot oxidize ubiquinol through center P, rates of reduction of cytochrome b by menaquinol through center N are normal.	menaquinol	147-157	cytochrome b	Saccharomyces cerevisiae S288C	131-143
