Special Issue Information

Dear Colleagues,

Algal light-harvesting antenna complexes (LHCs) are vital apparatus for energy capture and transfer in algal photosynthesis. Different from higher plants, algal LHCs are more diverse in terms of pigment compositions and structures. Within the past years, structures the antenna complexes have been elucidated with the help of technological development in structural biology, and the structural analysis of algal LHC shows a development trend of "low resolution in situ / single particle structure - high resolution single particle / in situ structure". Furthermore, the antennas transfer the absorbed energy at almost 100% efficiency to the reaction centres that perform the photochemical electron transfer reactions required for the conversion of the light energy into useful and storable chemical energy. The antenna complex has a broad cross-section of absorption and mainly transfers the absorbed energy to photosystem II. They can, however, function as an antenna of photosystem I, and their composition can be altered as a result of changes in the environmental light quality.

We invite researchers to contribute to the Special Issue titled “Structure and Energy Transfer of Photosynthetic Antenna Organism Crystals”, which is intended to serve as a unique multidisciplinary forum covering broad aspects of structural and functional characteristics of the photosynthetic antenna complex and the energy transfer mechanism in the complex. The potential topics include, but are not limited to, the following:

- Antenna complex assembly and disassembly

- Structure analysis using cryo-electron microscopy (Cryo-EM) or X-ray diffraction

- Antenna functional charateristics

- Energy transfer mechnisms in antenna

- Environmental adaption mechanisms of antenna

Abstract
The time-resolved fluorescence spectroscopy of the C−phycocyanin (C−PC) complex from the cyanobacterium Spirulina platensis (S. platensis) hexamer with the sub-picosecond resolution was detected, and the energy transfer pathways and related transfer rates were identified through the multiexponential analysis based on Monte-Carlo [...] Read more.
The time-resolved fluorescence spectroscopy of the C−phycocyanin (C−PC) complex from the cyanobacterium Spirulina platensis (S. platensis) hexamer with the sub-picosecond resolution was detected, and the energy transfer pathways and related transfer rates were identified through the multiexponential analysis based on Monte-Carlo method. With the purpose to construct the relationship between the functions and the structure in vivo, the three−dimension (3D) protein structure was predicted via AlphaFold2, and the arrangement of chromophores treated as the energy transfer nodes were obtained. The experiment results have been matched well with the structure prediction. This work suggests a new way to investigate structure prediction in vivo and the corresponding functions. Full article

As the largest light-harvesting complex in cyanobacteria, phycobilisomes (PBSs) show high efficiency and a high rate of energy transfer, owing to an elegant antenna-like assembly. To understand the structural influence on the dynamic process of the energy transfer in PBSs, two cyanobacterium species Thermosynechococcus vulcanus NIES 2134 (T. 2134) and Synechocystis sp. PCC 6803 (S. 6803) with different rod–core-linked assemblies were chosen for this study. The dynamic process of the energy transfer in both PBSs was investigated through time-resolved fluorescence spectroscopy (TRFS) with a time resolution of sub-picosecond. Via the fluorescence decay curves deconvolution, the pathways and related rates of the excitation energy transfer (EET) were determined. Three time components, i.e., 10, 80, and 1250 ps, were identified in the EET in the PBSs of T. 2134 and three, i.e., 9, 115, and 1680 ps, in the EET in the PBSs of S. 6803. In addition, a comparison of the dynamic process of the energy transfer between the two cyanobacteria revealed how the PBS assembly affects the energy transfer in PBSs. The findings will provide insight into future time-resolved crystallography. Full article
