The Effective Force Constant Approach of Protein Flexibility Applied to Selected Photosynthetic Protein Complexes [PDF]
MoleculesProteins are generally characterized by three-dimensional structures that are well suited for their specific function. It is much less accepted that a particular flexibility or plasticity of a protein is essential for performing its function.

A Diatom Light-Harvesting Pigment-Protein Complex [PDF]
Plant Physiology, 1984 A light-harvesting pigment-protein complex was isolated from the diatom Phaeodactylum tricornutum using the zwitterionic detergent CHAPS (3-[3-cholamidopropyl)dimethylammonio]-1-propanesulfonate). Detergent-solubilized membranes were fractionated by sucrose density gradient centrifugation into three components.

Biogeography of photosynthetic light-harvesting genes in marine phytoplankton. [PDF]
PLoS ONE, 2009 BACKGROUND: Photosynthetic light-harvesting proteins are the mechanism by which energy enters the marine ecosystem. The dominant prokaryotic photoautotrophs are the cyanobacterial genera Prochlorococcus and Synechococcus that are defined by two distinct ...

The Assembly of Super-Complexes in the Plant Chloroplast
Biomolecules, 2021 Increasing evidence has revealed that the enzymes of several biological pathways assemble into larger supramolecular structures called super-complexes. Indeed, those such as association of the mitochondrial respiratory chain complexes play an essential ...
