Influence of subunit structure on the oligomerization state of light harvesting complexes: a free energy calculation study

, 2005
Light harvesting complexes 2 (LH2) from Rhodospirillum (Rs.) molischianum and Rhodopseudomonas (Rps.) acidophila form ring complexes out of eight or nine identical subunits, respectively.

Methylation at the C-2 position of hopanoids increases rigidity in native bacterial membranes [PDF]

, 2015
Sedimentary rocks host a vast reservoir of organic carbon, such as 2-methylhopane biomarkers, whose evolutionary significance we poorly understand. Our ability to interpret this molecular fossil record is constrained by ignorance of the function of their

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 5, Page 1092-1103, May 2026.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Molecular analysis of the distribution and phylogeny of the soxB gene among sulfur-oxidizing bacteria - evolution of the Sox sulfur-oxidizing enzyme system [PDF]

, 2007
The soxB gene encodes the SoxB component of the periplasmic thiosulfate-oxidizing Sox enzyme complex, which has been proposed to be widespread among the various phylogenetic groups of sulfur-oxidizing bacteria (SOB) that convert thiosulfate to sulfate ...

MicrobeDiscover: A Knowledge Graph–Enabled AI Framework for Identifying Microbes for Inorganic Nanomaterial Biosynthesis

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Microbial synthesis of nanomaterials (NMs) is eco‐friendly, but the screening of microorganisms is limited by inefficient traditional methods (currently only involving∽400 microorganisms/90 NMs). We propose AI framework MicrobeDiscover, integrating a knowledge graph of microbe‐NM interactions.

The fox Operon from Rhodobacter Strain SW2 Promotes Phototrophic Fe(II) Oxidation in Rhodobacter capsulatus SB1003 [PDF]

, 2007
Anoxygenic photosynthesis based on Fe(II) is thought to be one of the most ancient forms of metabolism and is hypothesized to represent a transition step in the evolution of oxygenic photosynthesis.

Marine sponges as habitats of anaerobic phototrophic bacteria [PDF]

, 1976
Enrichment cultures were prepared with different media for phototrophic bacteria from four species of marine sponges, collected from oxic coastal waters near Split (Yugoslavia). We obtained pure cultures of six strains of Chromatiaceae and two strains of

Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis

ChemistryEurope, Volume 4, Issue 4, April 2026.
Biotic‐abiotic photosynthetic systems integrate light‐harvesting semiconductors with nitrogenase's selective N2 reduction under ambient conditions, offering a sustainable alternative to conventional ammonia synthesis. Advancing rational interface design, efficient energy‐reaction coupling, and system integration is critical to realizing scalable, solar‐

Quantitative hopanoid analysis enables robust pattern detection and comparison between laboratories [PDF]

, 2015
Hopanoids are steroid-like lipids from the isoprenoid family that are produced primarily by bacteria. Hopanes, molecular fossils of hopanoids, offer the potential to provide insight into environmental transitions on the early Earth, if their sources and ...
