| studies of photosynthesis using a pulsed laser. i. temperature dependence of cytochrome oxidation rate in chromatium. evidence for tunneling. | the rate of oxidation of cytochrome following absorption of a short pulse of light from a ruby laser in the photosynthetic bacterium chromatium has been measured spectrophotometrically. the half-time is about 2 musec at room temperature increasing to 2.3 msec at about 100 degrees k and constant at the latter value to 35 degrees k or below. the temperature dependence above 120 degrees k corresponds to an activation energy of 3.3 kcal/mole; that below 100 degrees k to less than 80 cal/mol: essenti ... | 1966 | 5972381 |

| changes in adenine nucleotides of intact chromatium d produced by illumination. | the total adenine nucleotide content of suspensions of chromatium d averaged 14 nmoles/mg of dry weight. of this, one-third to one-half was adenosine triphosphate (atp), even in suspensions incubated in darkness. illumination with high intensities caused a rise in atp and a drop mainly in adenosine diphosphate, the new steady state being reached in 5 to 15 sec at room temperature. the dark steady state was re-established 15 to 30 sec after returning the suspensions to darkness. the rates of thes ... | 1967 | 6025442 |
| biosynthesis of phenylalanine from phenylacetate by chromatium and rhodospirillum rubrum. | cultures of chromatium strain d and rhodospirillum rubrum incorporated (14)c from phenylacetate-1-(14)c during anaerobic growth. the radioactivity in the protein fraction of cells was mainly in phenylalanine. phenylalanine from chromatium cells grown in phenylacetate-1-(14)c was labeled at carbon 2. incorporation of phenylacetate by chromatium was decreased in the presence of exogenous phenylalanine, and de novo synthesis of phenylalanine from bicarbonate was less in medium containing either phe ... | 1967 | 6032506 |
| effect of oxygen on viability and substrate utilization in chromatium. | chromatium d can be exposed to oxygen for prolonged periods without any loss in motility or viability. oxygen did not affect the rate of thiosulfate disappearance from the media, the oxidation of the inner sulfur atom of thiosulfate to sulfate, or the conversion of the outer sulfur atom of thiosulfate to intracellular sulfur, but it did inhibit the oxidation of intracellular sulfur to sulfate. oxygen partially inhibited the uptake of pyruvate from the medium, but had little effect on the uptake ... | 1967 | 6032511 |

| thermodynamics of light emission and free-energy storage in photosynthesis. | a planck law relationship between absorption and emission spectra is used to compute the fluorescence spectra of some photosynthetic systems from their absorption spectra. calculated luminescence spectra of purple bacteria agree well but not perfectly with published experimental spectra. application of the planck law relation to published activation spectra for systems i and ii of spinach chloroplasts permits independent calculation of the luminescence spectra of the two systems; if the luminesc ... | 1967 | 6048879 |

| effect of thiol-binding reagents on the metabolism of chromatium d. | thiosulfate, intracellular sulfur, and acetate utilization by chromatium d were inhibited by iodoacetamide, n-ethylmaleimide (nem), p-hydroxymercuribenzoate (cmb), and hgcl(2). pyruvate, sulfide, and sulfite utilization were insensitive to iodoacetamide, and were less sensitive to nem, cmb, and hgcl(2) than thiosulfate, intracellular sulfur, and acetate utilization. the effect of the thiol-binding reagents on cell viability was dependent upon the method of exposure; cells exposed to the thiol-bi ... | 1968 | 5650077 |
| molecular diversity of the ribulose-1,5-diphosphate carboxylase from photosynthetic microorganisms. | the ribulose-1,5-diphosphate carboxylases from green and blue-green algae and the purple sulfur photosynthetic bacterium chromatium are proteins with high molecular weights and with sedimentation coefficients of 18 to 21 svedberg units. the carboxylases of the athiorhodaceae are smaller, that of rhodospirillum rubrum being a 6.2s molecule, and those of the two species of rhodopseudomonas are 12s and 14.5s. | 1968 | 5659689 |
