Acclimation of the photosynthetic apparatus to low light in a thermophilic Synechococcus sp. strain

Nathan Soulier et al.

Summary: Based on their growth responses to high and low irradiance, thermophilic Synechococcus sp. isolates from Mushroom Spring in Yellowstone National Park can be classified as high-light or low-light ecotypes. The low-light ecotypes show increased growth at low irradiance and develop far-red absorbance and fluorescence after growth in low light. These ecotypes have unique gene clusters encoding cyanobacteriochrome, sensor histidine kinase, far-red light absorbing allophycocyanin, and a chlorophyll a-binding protein. The emergence of far-red absorbance in low-light adapted cells is a result of a novel antenna complex containing far-red light absorbing allophycocyanin. Additionally, the two GAF domains of the cyanobacteriochrome LcyA bind different ligands that potentially enable this photoreceptor to respond to various environmental factors.

Chromatic Acclimation Processes and Their Relationships with Phycobiliprotein Complexes

Fanyue Wang et al.

Summary: Chromatic acclimation is a mechanism for optimizing light capture efficiency in cyanobacteria. Through genomic analysis, we identified different types of chromatic acclimation and their associated photoreceptors in cyanobacteria. We also found that different cyanobacteria have different capabilities for chromatic acclimation based on their genomic compositions and photoregulatory pathways.

Structures of a phycobilisome in light-harvesting and photoprotected states

Maria Agustina Dominguez-Martin et al.

Summary: In this study, the structures of Phycobilisome (PBS) in cyanobacteria were solved using cryogenic electron microscopy. The researchers discovered a previously unknown linker protein and revealed different conformational states of the antenna. Moreover, they elucidated the energy transfer pathways within PBS and provided insights into the control of cyanobacterial light harvesting, which has implications for bioengineering light-harvesting systems.

The structural basis of far-red light absorbance by allophycocyanins

Nathan Soulier et al.

Summary: Phycobilisomes (PBS) are the major light-harvesting antenna in cyanobacteria, composed of colorless linkers and pigment-binding phycobiliproteins, capable of absorbing orange-red and far-red light. Paralogous forms of AP have been identified recently, which can absorb far-red light and are used in two types of photoacclimation. Through site-specific mutagenesis, it was discovered that the protein environment surrounding the PCB on the AP alpha subunit is responsible for the far-red light absorbance of FRL-APs.

Highly accurate protein structure prediction with AlphaFold

John Jumper et al.

Summary: Proteins are essential for life, and accurate prediction of their structures is a crucial research problem. Current experimental methods are time-consuming, highlighting the need for accurate computational approaches to address the gap in structural coverage. Despite recent progress, existing methods fall short of atomic accuracy in protein structure prediction.

Recent advances in the structural diversity of reaction centers

Christopher J. Gisriel et al.

Summary: Photosynthetic reaction centers are crucial for converting light into chemical energy on Earth, with substantial diversity among different phyla. The recent study on the RC from a green sulfur bacterium challenges the canonical view of RC classification, revealing novel research directions. Common themes of electron donation, involvement of unknown Ca2+ site, lipid molecule in axial ligation, structural similarities with photosystem II, and energy quenching in GsbRC provide important insights into RC evolution and diversity.

Structural insight into the mechanism of energy transfer in cyanobacterial phycobilisomes

Lvqin Zheng et al.

Summary: The major light-harvesting systems for photosynthesis in cyanobacteria and red algae are phycobilisomes (PBS). Cryo-EM structures of two cyanobacterial PBS from Anabaena 7120 and Synechococcus 7002 reveal characteristics of their energy transfer pathways and the critical aromatic residues involved in excitation energy transfer (EET). The structures also suggest active participation of linker proteins in the process of EET within both rods and cores, providing insights into chromophore organization and EET mechanisms in cyanobacterial PBS.
