Photoreceptor Proteins from Purple Bacteria
2009Purple bacteria contain representatives of four of the six main families of photoreceptor proteins: phytochromes, BLUF domain containing proteins, xanthopsins (i.e., photoactive yellow proteins), and phototropins (containing one or more light, oxygen, or voltage (LOV) domains).

Purple Bacteria: Electron Acceptors and Donors
2013ABSTRACT: Purple bacteria form a heterogeneous group of microorganisms capable of growing under anoxic conditions by anoxygenic photosynthesis. They can be divided in purple non-sulfur bacteria, which are able to grow both phototrophically and in darkness, and purple sulfur bacteria, all of them capable to grow in the light but only few of them in the ...

Physiological ecology of purple and green bacteria
Annales de l'Institut Pasteur / Microbiologie, 1983Resume L'abondance des bacteries phototrophes dans la nature depend beaucoup du groupe etudie: les Chromatiacees et les Chlorobiacees se developpent souvent en abondance, alors que les Rhodospirillacees sont ubiquistes mais en petit nombre; les Chloroflexacees peuvent former des tapis sous une couche de cyanobacteries, mais leur presence dans des ...

Chaperoning Rubisco in Purple Bacteria
1996Rubisco (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 ...

Photosynthesis in the Purple Bacteria
2017Anoxygenic chlorophototrophic purple bacteria have long provided a useful model system for functional and structural studies of the light reactions of photosynthesis, since they possess only a single Type II photochemical reaction center (RC), while in the more complex oxygenic phototrophs, two types of RCs, designated as photosystems I and II, are ...

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.

Peripheral Complexes of Purple Bacteria
2009This 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.

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, 1995The 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
