Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]
, 2018 Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...

The structure of intact and active Photosystem II from Arabidopsis thaliana at 2.44 Å resolution
New Phytologist, EarlyView.Summary Photosystem II (PS II) is a large membrane‐bound protein complex that catalyses light‐driven water oxidation in plants and cyanobacteria. The structure of PS II is well studied in cyanobacteria; however, there are very few PS II structures from plants.

, 2013 Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

Bartolosides E–K from a Marine Coccoid Cyanobacterium [PDF]
Journal of Natural Products, 2016 The glycosylated and halogenated dialkylresorcinol (DAR) compounds bartolosides A-D (1-4) were recently discovered from marine cyanobacteria and represent a novel family of glycolipids, encoded by the brt biosynthetic gene cluster. Here, we report the isolation and NMR- and MS-based structure elucidation of monoglycosylated bartolosides E-K (5-11 ...

New Phytologist, EarlyView.Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...

Nitrogen-Fixing Cyanobacterium with a High Phycoerythrin Content [PDF]
Applied and Environmental Microbiology, 1989 The elemental and molecular composition, pigment content, and productivity of a phycoerythrin-rich nitrogen-fixing cyanobacterium—an Anabaena strain isolated from the coastal lagoon Albufera de Valencia, Spain—has been investigated.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
Plant, Cell &Environment, EarlyView.ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Sedimentology, EarlyView.ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

Tyrosine 263 in Cyanobacterial Phytochrome Cph1 Optimizes Photochemistry at the prelumi-R→lumi-R Step [PDF]
, 2014 We report a low-temperature fluorescence spectroscopy study of the PAS-GAF-PHY sensory module of Cph1 phytochrome, its Y263F mutant (both with known 3D structures) as well as Y263H and Y263S to connect their photochemical parameters with intramolecular ...
