The process of photosynthesis is initiated by the capture of sunlight by a network of light-
absorbing molecules (chromophores), which are also responsible for the subsequent …

Purple phototrophic bacteria are ancient anoxygenic phototrophs and attractive research
tools because they capture light energy in the near-infrared (NIR) region of the spectrum and …

After photoexcitation, energy absorbed by a molecule can be transferred efficiently over a
distance of up to several tens of angstroms to another molecule by the process of resonance …

The light-harvesting 1–reaction centre (LH1–RC) complex is a key functional component of
bacterial photosynthesis. Here we present a 2.9 Å resolution cryo-electron microscopy …

The genomes of some purple photosynthetic bacteria contain a multigene puc family
encoding a series of α-and β-polypeptides that together form a heterogeneous antenna of …

Phytol, a C20 alcohol esterifying the C-173 propionate, and Mg2+ ion chelated in the central
cavity, are conservative structural constituents of chlorophylls. To evaluate their …

Photoacoustic imaging provides high-resolution images at depths beyond the optical
diffusion limit. To broaden its utility, there is need for molecular sensors capable of detecting …

The light-harvesting-reaction center complex (LH1-RC) from the purple phototrophic
bacterium Thiorhodovibrio strain 970 exhibits an LH1 absorption maximum at 960 nm, the …

Spectroscopy forms the bridge between theory and experiment in the analysis of structure,
properties, and reactivity of functional molecules and molecular aggregates. Our knowledge …

Discovered 30 years ago, aerobic anoxygenic phototrophs (AAP) represent an entirely new
bacterial functional group that was surprisingly found to constitute nearly 10% of microbial …
