Complementary adaptations of bacterial membranes to low temperatures [PDF]

, 2022
The membrane of bacteria is a crucial component that separates the cell from its environment and forms the site of essential functions such as energy generation, nutrient uptake, and sensing.

Identification of acetylated diether lipids in halophilic Archaea

MicrobiologyOpen, Volume 11, Issue 3, June 2022., 2022
Archaea‐type ether lipids have been found recently in Bacillales. They are monoether lipids with a C35 isoprenoid chain and are diacetylated by the O‐acetyltransferase YvoF. Phylogenetic studies implied that YvoF homologs also occur in Halobacteria (Archaea).

Diversity and origin of carotenoid biosynthesis: its history of coevolution towards plant photosynthesis

New Phytologist, Volume 232, Issue 2, Page 479-493, October 2021., 2021
Summary The development of photosynthesis was a highlight in the progression of bacteria. In addition to the photosystems with their structural proteins, the photosynthesis apparatus consists of different cofactors including essential carotenoids.

Bacterioopsin-Mediated Regulation of Bacterioruberin Biosynthesis in Halobacterium salinarum [PDF]

Journal of Bacteriology, 2011
ABSTRACT Integral membrane protein complexes consisting of proteins and small molecules that act as cofactors have important functions in all organisms. To form functional complexes, cofactor biosynthesis must be coordinated with the production of corresponding apoproteins. To examine this coordination, we study bacteriorhodopsin

Opsin-Mediated Inhibition of Bacterioruberin Synthesis in Halophilic Archaea [PDF]

Journal of Bacteriology, 2017
ABSTRACTHalophilic archaea often inhabit environments with limited oxygen, and many produce ion-pumping rhodopsin complexes that allow them to maintain electrochemical gradients when aerobic respiration is inhibited. Rhodopsins require a protein, an opsin, and an organic cofactor, retinal.

Effect of Carbon Sources in Carotenoid Production from Haloarcula sp. M1, Halolamina sp. M3 and Halorubrum sp. M5, Halophilic Archaea Isolated from Sonora Saltern, Mexico

Microorganisms, 2021
The isolation and molecular and chemo-taxonomic identification of seventeen halophilic archaea from the Santa Bárbara saltern, Sonora, México, were performed. Eight strains were selected based on pigmentation.

The biosynthesis mechanism of bacterioruberin in halophilic archaea revealed by genome and transcriptome analysis. [PDF]

Appl Environ Microbiol
ABSTRACT Halophilic archaea are promising microbial cell factories for bacterioruberin (BR) production. BR is a natural product with multi-bioactivities, allowing potential application in many fields. In the previous work, a haloarchaeon Halorubrum sp.

Identification of carotenoids from the extremely halophilic archaeon Haloarcula japonica

Frontiers in Microbiology, 2014
The carotenoids produced by extremely halophilic archaeon Haloarcula japonica were extracted and identified by their chemical, chromatographic, and spectroscopic characteristics (UV-Vis and mass spectrometry).
