Amino Acid Sequence of Pwczcoccus denitrificans Cytochrome chsO*
The amino acid sequence of Paracoccus (formerly Micrococcus) denitrificans cytochrome chbO has been established by a combination of standard chemical techniques and interpretation of a 2.5 8, resolution x-ray electron density map. Peptides derived from a trypsin digest were chemically sequenced, and then ordered by fitting them to the density map. The amino acid compositions of chymotryptic pep...
متن کاملParacoccus denitrificans cytochrome c1 gene replacement mutants.
We describe the construction and characterization of gene replacement mutants for the respiratory chain component cytochrome c1 in the bacterium Paracoccus denitrificans. Its structural gene (fbcC) was inactivated by insertion of the kanamycin resistance gene, introduced into a suicide vector, and conjugated into Paracoccus; chromosomal mutants obtained by homologous recombination were selected...
متن کاملTurnover of cytochrome c oxidase from Paracoccus denitrificans.
The heme aa3 type cytochrome oxidase from Paracoccus denitrificans incorporated into vesicles with phospholipid reacts during turnover much as the oxidase from mitochondria does. The spectrophotometric changes observed at various wavelengths are closely similar, and the rate is about one-half of that for beef heart oxidase under the same conditions. The rate of appearance of oxidized cytochrome...
متن کاملSolubilized cytochrome c oxidase from Paracoccus denitrificans is a monomer.
Cytochrome c oxidase purified from the bacterium Paracoccus denitrificans was analyzed by analytical ultracentrifugation. In the detergent octyltetra/pentaoxyethylene (C8E45), the isolated enzyme exhibits a molecular weight of 79,000 to 84,000. The detergent-solubilized enzyme is thus a monomer which contains one copy of each of the two subunits.
متن کاملThe Amino Acid Sequence of Cytochrome b,*
Calf liver microsomal apocytochrome bs was hydrolyzed with chymotrypsin and the resulting peptides were resolved on a Dowex 1 column. The isolation and partial amino acid sequences of the 10 chymotryptic peptides are described. The total amino acid composition of these peptides is equal to the sum of the residues present in the tryptic peptides. On the basis of the data obtained for the chymotr...
