Valinomycin 33-44 cytochrome c, somatic Homo sapiens 100-112 2158497-1 1990 The K(+)-ionophores valinomycin and nonactin induce a qualitatively identical change of the visible spectrum of isolated oxidized cytochrome c oxidase (red shift), but the amplitude is half with nonactin. Valinomycin 20-31 cytochrome c, somatic Homo sapiens 130-142 2158497-2 1990 Valinomycin, in the presence or absence of a protonophore, stimulates the respiration of the reconstituted enzyme to a higher extent than nonactin and results in a higher Km for cytochrome c. Valinomycin 0-11 cytochrome c, somatic Homo sapiens 178-190
