Structural and functional analysis of deficient mutants in subunit I of cytochrome c oxidase from Saccharomyces cerevisiae

Autor: Brigitte Meunier, Ulrich Brandt, Claus Ortwein, Peter R. Rich, Anne-Marie Colson-Corbisier, Thomas A. Link

Publikováno v: Biochimica et Biophysica Acta (BBA) - Bioenergetics. 1321:79-92

Four point mutations in subunit I of cytochrome c oxidase from Saccharomyces cerevisiae that had been selected for respiratory incompetence but still contained spectrally detectable haem aa(3) were analysed. The isolated mutant enzymes exhibited mino

Analysis of revertants from respiratory deficient mutants within the centerNof cytochromebinSaccharomyces cerevisiae

Autor: Anne-Marie Colson, Hideto Miyoshi, Jean-Yves Coppée, J P di Rago, D Marc, N Tokutake

Publikováno v: FEBS Letters. 339:1-6

Four modified cytochrome b's carrying mononucleotide substitutions affecting center N residues were analysed. The mutant carrying a G33D change does not incorporate heme into the apocytochrome b and fails to grow on non-fermentable carbon sources. Ou

Non-native intragenic reversions selected from Saccharomyces cerevisiae cytochrome b-deficient mutants. Structural and functional features of the catalytic center N domain

Publikováno v: Journal of Biological Chemistry. 269:4221-4226

A total of 110 revertants have been isolated from two well-characterized cytochrome b deficient (mit-) mutants. The mit- mutations are located in an extramembranous loop linking the transmembrane alpha-helices IV and V of cytochrome b which has been

Rapid screening of cytochromes of respiratory mutants of Saccharomyces cerevisiae. Application to the selection of strains containing novel forms of cytochrome-c oxidase

Autor: Simon H. J. Brown, Anne-Marie Colson, Brigitte Meunier, Peter R. Rich

Publikováno v: European Journal of Biochemistry. 213:137-145

A technique has been developed for the direct analysis by visible spectrophotometry of yeast spots growing on agar plates. This allows rapid semi-quantitative estimations of cytochromes c, b and oxidase and permits the identification of strains with

Point mutation in cytochrome b of yeast ubihydroquinone:cytochrome-c oxidoreductase causing myxothiazol resistance and facilitated dissociation of the iron-sulfur subunit

Autor: Anne-Marie Colson, Gebhard von Jagow, B. M. Geier, Ulrich Brandt, Hermann Schägger

Publikováno v: European Journal of Biochemistry. 208:375-380

Cytochrome-c reductase was isolated from Saccharomyces cerevisiae GM50-3C. A tenth subunit was detected with molecular mass 8.5 kDa on SDS/PAGE. Two yeast mutants selected for resistance to myxothiazol, an inhibitor of the Q(0) center (Q, ubiquinone)

Molecular analysis of revertants from a respiratory-deficient mutant affecting the center o domain of cytochromebinSaccharomyces cerevisiae

Autor: Anne-Marie Colson, Jean-Yves Coppée, Thierry Tron, Pascale Infossi

Publikováno v: FEBS Letters. 278:26-30

Inbc complexes, cytochromeb plays a major role in electron transfer and in proton translocation accross the membrane. Several inhibitor-resistant and respiratory-deficient mutants have already been used to study the structure-function relationships o

The topology of CuA in relation to the other metal centres in cytochrome-c oxidase of Saccharomyces cerevisiae as determined by analysis of second-site reversions

Autor: Peter R. Rich, Anne-Marie Colson, Brigitte Meunier

Publikováno v: Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology. 1253:13-15

Second-site revertants were selected from a respiratory-deficient mutant carrying the mutation D369N located in a loop between helices IX and X close to H376 and H378, the proposed ligands of haem a(3) and haem a, respectively. A reversion was observ
