Antimycin A 0-11 cytochrome b Saccharomyces cerevisiae S288C 188-200 2517475-2 1989 The results concerning the structure-function relationship of cytochrome b in this complex, analyzed within the framework of the eight transmembrane alpha helice cytochrome b folding model, agree with the following features of the proton motive Q cycle (or SQ cycle): i) the antimycin A and myxothiazol binding domains are located on opposite sides of the inner mitochondrial membrane; and ii) the antimycin A binding domain is associated with the b562 domain, the myxothiazol domain with the b565 domain. Antimycin A 275-286 cytochrome b Saccharomyces cerevisiae S288C 62-74 2517475-2 1989 The results concerning the structure-function relationship of cytochrome b in this complex, analyzed within the framework of the eight transmembrane alpha helice cytochrome b folding model, agree with the following features of the proton motive Q cycle (or SQ cycle): i) the antimycin A and myxothiazol binding domains are located on opposite sides of the inner mitochondrial membrane; and ii) the antimycin A binding domain is associated with the b562 domain, the myxothiazol domain with the b565 domain. Antimycin A 398-409 cytochrome b Saccharomyces cerevisiae S288C 62-74 2517475-4 1989 However, functional studies are reported here that are not in agreement with the following features of the above models: i) the serial arrangement of the two hemes of cytochrome b and ii) the isolation of cytochrome b from redox changes with the couple fumarate/succinate in the presence of antimycin A and myxothiazol. Antimycin A 291-302 cytochrome b Saccharomyces cerevisiae S288C 205-217 2615656-0 1989 Mitochondrial cytochrome b genes with a six-nucleotide deletion or single-nucleotide substitutions confer resistance to antimycin A in the yeast Kluyveromyces lactis. Antimycin A 120-131 cytochrome b Saccharomyces cerevisiae S288C 14-26 6262574-1 1980 Complex III isolated from yeast mitochondria catalyzed an antimycin A and Diuron-sensitive coenzyme QH2-cytochrome c reductase activity with a turnover number of 15.7 sec(-1) and contained 10 nmoles of cytochrome b and 4.6 nmoles of cytochrome c1 per mg of protein. Antimycin A 58-69 cytochrome b Saccharomyces cerevisiae S288C 202-214 7002556-5 1980 Two different methods have been used to determine the cytochrome b-565 content: anaerobic titrations and antimycin-A-induced reduction of cytochrome b-565. Antimycin A 105-116 cytochrome b Saccharomyces cerevisiae S288C 54-66 7002556-5 1980 Two different methods have been used to determine the cytochrome b-565 content: anaerobic titrations and antimycin-A-induced reduction of cytochrome b-565. Antimycin A 105-116 cytochrome b Saccharomyces cerevisiae S288C 138-150 19224349-7 2009 Our results suggest that lipoperoxidation impairs electron transfer mainly at cytochrome b in complex III, which leads to increased resistance to antimycin A and ROS generation due to an electron leak at the level of the Q(O) site of complex III. Antimycin A 146-157 cytochrome b Saccharomyces cerevisiae S288C 78-90 340894-4 1977 The mapping relationship of mutants resistant to antimycin A or funiculosin to various cob mutants is described. Antimycin A 49-60 cytochrome b Saccharomyces cerevisiae S288C 87-90 5533677-0 1970 Interactions of uncoupling agents and of antimycin A with cytochrome b in yeast and heart muscle preparation under anaerobic conditions. Antimycin A 41-52 cytochrome b Saccharomyces cerevisiae S288C 58-70 28960782-5 2018 In Saccharomyces cerevisiae, amino acid substitutions N31K, G37C and L198F at the Qi quinone binding site of cytochrome b reduced sensitivity to fenpicoxamid, UK-2A and antimycin A. Antimycin A 169-180 cytochrome b Saccharomyces cerevisiae S288C 109-121
