Pyruvate Carboxylase in Rhodopseudomonas spheroides [PDF]

Journal of General Microbiology, 1969
SUMMARY: Unlike some other photosynthetic bacteria, Rhodopseudomonas spheroides directly carboxylates pyruvate in a reaction catalysed by a pyruvate carboxylase (E.C. 6·4.1·1). A partially purified preparation of the enzyme was acetylCoA-dependent. No phosphoenolpyruvate synthetase or phosphoenolpyruvate carboxylase activity was detected in extracts of

Clades of Photosynthetic Bacteria Belonging to the Genus Rhodopseudomonas Show Marked Diversity in Light-Harvesting Antenna Complex Gene Composition and Expression

mSystems, 2016
Many photosynthetic bacteria have peripheral light-harvesting (LH) antenna complexes that increase the efficiency of light energy capture. The purple nonsulfur photosynthetic bacterium Rhodopseudomonas palustris produces different types of LH complexes ...

Hydrogen recycling by Rhodopseudomonas capsulata [PDF]

FEBS Letters, 1977
capsdata evolves large quantities of molecular Hz via an energy-dependent nitrogenase activity when grown photoheterotrophically and supplied with certain amino acids, e.g., glutamate, as nitrogen source [ 1,2]. In addition, these bacteria are capable of utilizing Hz as a reductant for photoautotrophic growth.

The Composition of Intestinal Microbiota From Collichthys lucidus and Its Interaction With Microbiota From Waters Along the Pearl River Estuary in China

Frontiers in Environmental Science, 2021
By their nature and geographical location, estuaries shape different marine habitats via freshwater and seawater interactions. Thus, fish intestinal microbiota, as mediated by estuary habitat fluctuations, are fundamentally important but rarely studied ...

Spectroscopic characterization of reaction centers of the (M)Y210W mutant of the photosynthetic bacterium Rhodobacter sphaeroides [PDF]

, 1994
The tyrosine-(M)210 of the reaction center of Rhodobacter sphaeroides 2.4.1 has been changed to a tryptophan using site-directed mutagenesis. The reaction center of this mutant has been characterized by low-temperature absorption and fluorescence ...

Substrate specificity of citrate lyase deacetylase of Rhodopseudomonas gelatinosa and Rhodopseudomonas palustris [PDF]

Journal of Bacteriology, 1981
Citrate lyase (EC 4.1.3.6) isolated from Rhodopseudomonas palustris was investigated with regard to its kinetic properties and its subunit composition. This enzyme was inactivated by citrate lyase deacetylase (EC 3.1.2.-) of Rhodopseudomonas gelatinosa. A corresponding cross-reaction was measured with partially purified deacetylase of R.

Alternative microbial-based functional ingredient source for lycopene, beta-carotene, and polyunsaturated fatty acids

Heliyon, 2023
The acquisition of carotenoids and polyunsaturated fatty acids (PUFAs) from plants and animals for use as functional ingredients raises concerns regarding productivity and cost; utilization of microorganisms as alternative sources is an option.

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.
