| the amino acid sequence of cytochrome c' from alcaligenes sp. n.c.i.b. 11015. | the amino acid sequence of the cytochrome c' from alcaligenes sp. n.c.i.b. 11015 (iwasaki's ;pseudomonas denitrificans') has been determined. this organism is the only non-photosynthetic bacterium in which the protein has been found. the protein consists of a single polypeptide chain of 127 residues, with a single haem covalently attached to two cysteines. unlike normal cytochromes c, the haem attachment site is very close to the c-terminus. the amino acid sequence around the haem attachment sit ... | 1973 | 4360249 |

| on the monohene character of cytochromes c'. | interpretations of data bearing on structures of cytochromes cc'-a class of variant c-type heme proteins from bacteria-in support of a diheme-bearing single chain as a basic structural unit, appear to be invalid in the light of recent studies. these reveal that nearly all members of this class exist as dimers that can be dissociated into, if they do not already exist as, monoheme-bearing monomers. the particular case of the chromatium protein, held to be the source of a peptic-"core" peptide con ... | 1972 | 4343972 |

| coproporphyrinogenase activities in extracts of rhodopseudomonas spheroides and chromatium strain d. | 1. the anaerobic coproporphyrinogenase activity in an extract of rhodopseudomonas spheroides is inhibited by 1,10-phenanthroline, alphaalpha'-bipyridyl, flavins, 2,4-dinitrophenol and 1,4-naphthaquinone. these compounds have no effect on the aerobic coproporphyrinogenase activity. 2. on removal of small-molecular-weight material from a crude extract, the anaerobic system becomes very unstable; it can be stabilized by adding succinate. now nicotinamide nucleotides, in addition to mg(2+), atp and ... | 1972 | 4345352 |

| observations on light-induced oxidation reactions in the electron transport system of chromatium. | light-induced cytochrome oxidations in chromatium subchromatophore particles were studied in detail. these reactions were found to be dependent not only on redox potential, but also on the efficiency of coupling of the redox buffer electrons to the cytochrome system. light-induced oxidation of the high potential cytochrome (c-556) was dependent on (a) the availability of reduced cytochrome and (b) the rate of light-induced oxidation (as determined by light intensity) vs. rate of cytochrome rered ... | 1972 | 5037342 |

| biocarbonate effect on the photophosphorylation catalyzed by chromatophores isolated from chromatium strain d: xii. structure and function of chloroplast proteins. | photophosphorylation catalyzed by chromatophores prepared from chromatium strain d was stimulated by bicarbonate. the stimulative effect was ph dependent and the lower the ph the more marked the activation. at ph 8.0, bicarbonate (8 mm) exhibited a negligible effect, whereas at ph 7.0 approximately a 5-fold activation was observed. the apparent activation constant of bicarbonate was determined to be approximately 10.2 mm, at which concentration approximately a 7-fold activation of photophosphory ... | 1972 | 16658218 |
