proton magnetic resonance studies of chromatium high-potential iron protein.contact-shifted nuclear magnetic resonances, arising from molecular paramagnetism, have been observed in both reduced and oxidized forms of the high-potential iron protein (hipip) isolated from chromatium. contact shifts of the reduced, formally diamagnetic form increase with temperature, indicating antiferromagnetic exchange coupling of the component iron atoms with thermal population of a magnetic state. in the oxidized form of hipip (formally s = 1/2), contact-shifted resonances attributed to ...19705289015

thermodynamics and the primary processes of photosynthesis.numerous discussions of the relationship of the thermodynamics of radiation to photosynthesis have been published, but the results are often in disagreement or at best difficult to compare with one another. the recent treatment of maximal photosynthetic efficiencies by ross and calvin is here shown to be directly related to the thermodynamic method of duysens. a smooth connection between the light and dark conditions is derived, the case of polarized light is considered briefly, and a critique o ...19695353140
amino acid composition and terminal sequences of ferredoxins from two photosynthetic green bacteria.the amino acid composition of ferredoxins from chlorobium thiosulfatophilum 8327 and chloropseudomonas ethylicum, like c. thiosulfatophilum tassajara, resembled ferredoxins from nonphotosynthetic anaerobes rather than chromatium; the terminal sequences, however, more closely resembled chromatium ferredoxin.19695361222

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 ...19685650077
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.19685659689
