Photophysics of plasmonically enhanced self-assembled artificial light-harvesting nanoantennas

Communications Chemistry
The design of efficient artificial light-harvesting antennas is essential for enabling the widespread use of solar energy. Natural photosynthetic systems offer valuable inspiration, but many rely on complex pigment–protein interactions and have limited ...

Terrestrial Plants Evolve Highly Assembled Photosystem Complexes in Adaptation to Light Shifts

Frontiers in Plant Science, 2018
It has been known that PSI and PSII supercomplexes are involved in the linear and cyclic electron transfer, dynamics of light capture, and the repair cycle of PSII under environmental stresses.

The C‐Terminal Domain of Light‐Harvesting Chlorophyll‐a/b‐Binding Protein is Involved in the Stabilisation of Trimeric Light‐Harvesting Complex [PDF]

European Journal of Biochemistry, 1996
Light‐harvesting chlorophyll a/b‐binding protein (LHCP) can be reconstituted with pigments in detergent solution to yield stable monomeric light‐harvesting chlorophyll a/b complex (LHCII). This reconstitution is not significantly affected when up to ten amino acids are deleted on the C‐terminus of LHCP or when a tryptophan, which is 11 positions from ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Light-Harvesting Chlorophyll a/b-Binding Protein Inserted into Isolated Thylakoids Binds Pigments and Is Assembled into Trimeric Light-Harvesting Complex [PDF]

Plant Physiology, 1995
The light-harvesting chlorophyll a/b-binding protein (LHCP) is largely protected against protease (except for about 1 kD on the N terminus) in the thylakoid membrane; this protease resistance is often used to assay successful insertion of LHCP into isolated thylakoids in vitro.

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Arabidopsis STN7 Kinase Provides a Link between Short- and Long-Term Photosynthetic Acclimation [PDF]

, 2009
Flowering plants control energy allocation to their photosystems in response to light quality changes. This includes the phosphorylation and migration of light-harvesting complex II (LHCII) proteins (state transitions or short-term response) as well as ...

Structural Basis of Photosystem I and Its Photosynthesis Regulation in Green Plants

Shengwu huaxue yu shengwu wuli jinzhan
Photosynthesis is one of the most important chemical reactions on earth. Oxygenic photosynthetic organisms convert solar energy into chemical energy and release oxygen, thus sustaining almost all life on this planet.

Light-harvesting complex II in monocomponent and mixed lipid-protein monolayers

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1998
Monomolecular layers at the air-water interface were formed directly with isolated largest light-harvesting pigment-protein complex of Photosystem II (LHC II) or out of egg yolk lecithin (EYL) liposomes containing incorporated LHC II. Pure protein monolayers showed a mean area of 1400 A2 per molecule at the air-water interface.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
