Phototaxis of purple bacteria

1959
Phototaxis in the purple bacteria is linked to the absorption of energy by the type of chlorophyll which is present. Taxes in general appear to be related, in the purple bacteria, to the metabolic activities which support growth. In the green algae, flagellates, and gametes of higher plants phototaxis in not related to energy absorbed by chlorophyll.

Chaperoning Rubisco in Purple Bacteria

1996
Rubisco (ribulose 1,5-bisphosphate carboxylase/oxygenase) has played a pivotal role in the identification of the so-called molecular chaperones (Ellis 1994; Hartman, Harpel 1994), families of highly conserved proteins present in all organisms which play fundamental roles in the assembly, transport and degradation of cellular polypeptides as well as in ...

Peripheral Complexes of Purple Bacteria

2009
This chapter uses the LH2 complex from Rhodopseudomonas acidophila strain 10050 as an example to describe the current understanding of the structure of purple bacterial peripheral antenna complexes. It summarizes both what is and what is not understood.

Bacteria brew prized purple

C&EN Global Enterprise, 2020
In the days of the Roman Empire, Tyrian purple dye cost more than gold. The rare and royal pigment had to be painstakingly extracted from Murex brandaris sea snails—as many as 10,000 of the mollusk...

Light-harvesting mechanisms in purple photosynthetic bacteria

Current Opinion in Structural Biology, 1995
The processes by which photosynthetic bacteria capture light and transfer the energy to the reaction centre continue to be studied using an array of methodologies, both physical and biological. With the publication this year of the crystal structure of the LH2 complex from Rhodopseudomonas acidophila and the projection structure of the LH1 complex from

Taxonomy of phototrophic green and purple bacteria: A review

Annales de l'Institut Pasteur / Microbiologie, 1983
The presently existing classification for the green and purple bacteria comprises physiological-ecological assemblages of phototrophic bacteria with anoxygenic photosynthesis. The taxonomic units of the different levels were based entirely on common phenotypic traits, including morphological, cytological, physiological and biochemical characteristics ...

[Use of urea by purple bacteria].

Mikrobiologiia, 1979
Strains of purple sulfur bacteria (Chromatium minutissimum, Ectothiorhodospira shaposhnikovii, Thiocapsa roseopersicina, Lamprobacter modestohalophilus) and nonsulfur bacteria (Rhodopseudomonas palustris, Rh. spheroides, Rhodospirillum rubrum) grow in media containing urea as a source of nitrogen at concentrations from 0.5 to 5.0%.

Photophosphorylation by isolated chromatophores of the purple sulfur bacteria

Archives of Biochemistry and Biophysics, 1958
Abstract Chromatophores were isolated from the photosynthetic purple sulfur bacterium, Chromatium strain D. These particles were capable of a light-dependent esterification of ADP and inorganic phosphate with the resulting formation of ATP. Phosphorylation was stimulated by the supernatant from the ruptured cells.

Molecular genetics of purple bacteria

1996
Abstract In 1957 Cohen-Bazire et al. (1), noted that light intensity, as well as O2 tension could dramatically and immediately alter the cellular bacteriochlorophyll (Bchl) content of photosynthetically growing cultures of Rhodobacter sphaeroides.
