Publisher Summary Bacterial chromatophores exhibit certain biochemical properties similar to those of chloroplasts and are comparable to those of plant or animal mitochondria. For instance, chromatophores carry out cyclic photophosphorylation similar to that of chloroplasts; on the other hand, chromatophores, like mitochondria, catalyze a dark ...

Chromatophores (Chr) from photosynthetic nonsulfur purple bacterium Rhodobacter sphaeroides immobilized onto a Millipore membrane filter (MF) and sandwiched between two semiconductor indium tin oxide (ITO) electrodes (termed ITO|Chr - MF|ITO) have been used to measure voltage (ΔV) induced by continuous illumination.

Generation of photoelectric potential in chromatophores of Rhodopseudomonas sphaeroides has been measured (i) spectrophotometrically, using electrochromic shift of carotenoid absorption band or (ii) electrometrically, by means of two electrodes separated by a collodion film covered on one side with chromatophores. A 15 ns laser flash was used to induce

Absorption spectra of bacterial chromatophores at temperatures from 300° K to I° K
Biochimica Et Biophysica Acta, 1961Abstract Absorption spectra of chromatophores from R. spheroides and from Chromatium have been measured at temperatures from 300° K to 1.3° K. The absorption bands of bacteriochlorophyll are narrowed and intensified slightly, but not dramatically, at low temperature. The spectrum of R.

The role of a reaction center in photochemical activities of bacterial chromatophores
Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1965Abstract Strain PM-8 of Rhodopseudomonas spheroides is unable to grow photosynthetically even though it generates a normal complement of bacteriochlorophyll and carotenoids when grown aerobically in the dark. This mutant strain fails to show any of the light reactions, observable in the photosynthetically competent parent strain, that signal the ...

On the functional unit of energy coupling in photophosphorylation by bacterial chromatophores
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1983Abstract (1) Putative relationships between the rate of photophosphorylation, the proton-motive force and the concentration of an uncoupling molecule are considered within the framework of the delocalised chemiosmotic coupling hypothesis. The addition of a partially inhibitory titre of a specific, tight-binding H+-ATP synthase inhibitor is not ...
