Energy transfer processes in the isolated core antenna complexes CP43 and CP47 of photosystem II

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2010
The energy equilibration and transfer processes in the isolated core antenna complexes CP43 and CP47 of photosystem II have been studied by steady-state and ultrafast (femto- to nanosecond) time-resolved spectroscopy at room temperature. The annihilation-free femtosecond absorption data can be described by surprisingly simple sequential kinetic models,

Isolation of phosphorylated and dephosphorylated forms of the CP43 internal antenna of photosystem II in Hordeum vulgare L. [PDF]

Journal of Experimental Botany, 2005
As a consequence of variation in environmental factors, light being the most important one, a number of photosystem II polypeptides may be reversibly phosphorylated by thylakoid-bound kinase(s). Among them, the reaction centre D1 and D2 polypeptides, the PsbH subunit, and the inner antenna CP43.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, Volume 600, Issue 2, Page 164-187, January 2026.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Recombinant Proteins: A Molecular Tool to Understand Marine Adhesion and to Advance Biomaterials

Advanced Healthcare Materials, Volume 15, Issue 3, 19 January 2026.
The production of recombinant proteins represents a fundamental step in the characterisation of marine invertebrate adhesives and in the development of bio‐inspired glues. The association of these proteins with other components such as ions, proteins, polysaccharides, or polymers enables the fabrication of biomaterials for various healthcare ...

Biogenic Next‐Gen CPL Emitters: Strategies with Proteins, Polysaccharides, and Nucleotides

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Biogenic molecules such as proteins, peptides, saccharides, and DNA can act as natural scaffolds for generating circularly polarized luminescence (CPL). This review highlights recent strategies exploiting these inherently chiral frameworks to achieve light emission with controllable handedness under unpolarized excitation, bridging biological ...

Differences in photosystem II activity and carbon allocation during photomixotrophic growth in distinct wild‐type strains of Synechocystis sp. PCC 6803

The Plant Journal, Volume 125, Issue 2, January 2026.
SUMMARY The regulation of photosynthetic electron transport during photomixotrophic growth in cyanobacteria remains incompletely understood. In this study, we characterized four wild‐type strains (WT 1–4) of Synechocystis sp. PCC 6803 and observed distinct strain‐specific differences in photosystem II (PSII) function under photomixotrophic conditions ...

Molecular Electronic Devices for Protection and Control of Photoenergetic and Electrocatalytic Processes in the Light Phase of Photosynthesis

International Journal of Photoenergy, Volume 2026, Issue 1, 2026.
The article examines the energetic processes of the light‐dependent phase of photosynthesis. It explores the nature of energy and charge transport in molecules containing isoprene and isoprenyl bonds. A mechanism is proposed for the operation of a quantum current generator—Mn4O5Ca(Н2О)4 proceeding through the formation of electron–hole pairs. The study

The potential of TAOK1 as a new therapeutic target for the treatment of cancer cachexia-associated muscle atrophy

Pharmacological Research
Cancer cachexia, a multifactorial metabolic syndrome impacts 50–80 % cancer patients, is mainly characterized by skeletal muscle atrophy. In this study, we demonstrated that the thousand-and-one amino acid kinase 1 (TAOK1) was activated in both C2C12 ...

Early detection of infants with neurodevelopmental concerns indicative of cerebral palsy in a lower middle‐income country (India)

Developmental Medicine &Child Neurology, Volume 67, Issue 12, Page 1554-1563, December 2025.
In this prospective sub‐study testing the predictive validity of General Movements Assessment (GMA) and/or Hammersmith Infant Neurological Examination (HINE), 785 infants with birth/infant‐detectable risk factors, aged 12 to 40 weeks corrected age were recruited. GMA and HINE were reliable and accurate tools for screening high‐risk populations in India,

Are honey bees altering wild plant–bee interactions in reconstructed native habitats? An investigation of summer season effects in row‐crop agroecosystems with prairie strips

Ecological Entomology, Volume 50, Issue 5, Page 807-823, October 2025.
We investigated the compatibility of beekeeping with pollinator conservation in ‘prairie strips’ a conservation practice integrating native prairie habitat into agricultural environments. At prairie strip sites with and without a honey bee apiary, we analysed plant–bee interactions and bumble bee body conditions to determine the effect of apiaries on ...
