| [calculation of spectra of absorption and circular dichroism of rhodopseudomonas acidophila light harvesting complexes based on roentgen structural data]. | absorption and circular dichroism spectra of two forms of the peripheral light-harvesting complex from photosynthetic purple bacteria rhodopseudomonas acidophila were calculated. calculations were carried out on the basis of exciton theory for circular aggregates of bacteriochlorophyll molecules and x-ray data for these forms of the complex. it was shown that theoretical spectra fit well experimental ones at the same values of excitation energy, homogeneous and inhomogeneous broadening, and band ... | 2003 | 12723345 |
| some properties of glycine aminotransferase purified from rhodopseudomonas palustris no. 7 concerning extracellular porphyrin production. | glycine aminotransferase (ec 2.6.1.4; glyat) was presumed to be an enzyme concerning the supply of glycine for the extracellular porphyrin production by rhodopseudomonas palustris no. 7. glyat was purified from strain no. 7 as an electrophoretically homogenous protein. the enzyme was a monomer protein with the molecular weight of about 42,000. from the absorption spectrum of the enzyme (350 nm, 410 nm), it was indicated that the enzyme had pyridoxal phosphate as a prosthetic group. the enzyme sh ... | 2003 | 12784618 |
| influence of carotenoid molecules on the structure of the bacteriochlorophyll binding site in peripheral light-harvesting proteins from rhodobacter sphaeroides. | in the lh2 proteins from rhodobacter (rb.) sphaeroides, the hydrogen bonds between the bacteriochlorophyll (bchl) molecules and their proteic binding sites exhibit a strong variance with respect to carotenoid content and type. in the absence of the carotenoid molecule, such as in the lh2 from rb. sphaeroides r26.1, the void in the protein structure induces a significant reorganization of the binding site of both bchl molecules responsible for the 850 nm absorption, which is not observed when the ... | 2003 | 12795622 |
| afm imaging of bacteria in liquid media immobilized on gelatin coated mica surfaces. | immobilization of particulates, especially biomolecules and cells, onto surfaces is critical for imaging with the atomic force microscope (afm). in this paper, gelatin coated mica surfaces are shown to be suitable for immobilizing and imaging both gram positive, staphylococcus aureus, and gram negative, escherichia coli, bacteria in both air and liquid environments. gelatin coated surfaces are shown to be superior to poly-l-lysine coated surfaces that are commonly used for the immobilization of ... | 2003 | 12801673 |
| multichannel carotenoid deactivation in photosynthetic light harvesting as identified by an evolutionary target analysis. | a new channel of excitation energy deactivation in bacterial light harvesting was recently discovered, which leads to carotenoid triplet population on an ultrafast timescale. here we show that this mechanism is also active in lh2 of rhodopseudomonas acidophila through analysis of transient absorption data with an evolutionary target analysis. the algorithm offers flexible testing of kinetic network models with low a priori knowledge requirements. it applies universally to the simultaneous fittin ... | 2003 | 12829499 |
| in most bradyrhizobium groups sequence comparison of 16s-23s rdna internal transcribed spacer regions corroborates dna-dna hybridizations. | in an extension of a previous small-scale test to assess the use of 16s-23s rdna internal transcribed spacer (its) sequences for rapid grouping of bradyrhizobia, we have sequenced the its region of 32 isolates of bradyrhizobium that had previously been studied using aflp and dna-dna hybridizations. we also included representatives of afipia and rhodopseudomonas. our results indicate that its sequences are very diverse among bradyrhizobia. nevertheless, for most of the bradyrhizobia, the grouping ... | 2003 | 12866847 |

| changing concepts in the systematics of bacterial nitrogen-fixing legume symbionts. | as of february 2003, bacteria that form nitrogen-fixing symbiotic associations with legumes have been confirmed in 44 species of 12 genera. phylogenies of these taxa containing legume symbionts based on the comparative analysis of 16s rdna sequences show that they are not clustered in one lineage but are distributed in the classes alphaproteobacteria and betaproteobacteria, and dispersed over the following nine monophyletic groups, being intermingled with other taxa that do not contain legume sy ... | 2003 | 12949698 |
| biogeography of the purple nonsulfur bacterium rhodopseudomonas palustris. | the biogeography of the purple nonsulfur bacterium rhodopseudomonas palustris on a local scale was investigated. thirty clones of phototrophic bacteria were isolated from each of five unevenly spaced sampling locations in freshwater marsh sediments along a linear 10-m transect, and a total of 150 clones were characterized by box-pcr genomic dna fingerprinting. cluster analysis of 150 genomic fingerprints yielded 26 distinct genotypes, and 106 clones constituted four major genotypes that were rep ... | 2003 | 12957900 |
| spatial distribution of rhodopseudomonas palustris ecotypes on a local scale. | the number, spatial distribution, and significance of genetically distinguishable ecotypes of prokaryotes in the environment are poorly understood. oda et al. (y. oda, b. star, l. a. huisman, j. c. gottschal, and l. j. forney, appl. environ. microbiol. 69:xxx-xxx, 2003) have shown that rhodopseudomonas palustris ecotypes were lognormally distributed along a 10-m transect and that multiple strains of the species could coexist in 0.5-g sediment samples. to extend these observations, we investigate ... | 2003 | 12957901 |
| tuning heme redox potentials in the cytochrome c subunit of photosynthetic reaction centers. | the photosynthetic reaction center (rc) from rhodopseudomonas viridis contains four cytochrome c hemes. they establish the initial part of the electron transfer (et) chain through the rc. despite their chemical identity, their midpoint potentials cover an interval of 440 mv. the individual heme midpoint potentials determine the et kinetics and are therefore tuned by specific interactions with the protein environment. here, we use an electrostatic approach based on the solution of the linearized ... | 2003 | 12975370 |
