The influence of carotenoids on the conformation of chlorophyll-protein complexes isolated from the cyanobacterium Plectonema boryanum. Absorption and circular dichroism study
TLDR
Hladik et al. as mentioned in this paper showed that fraction III is an oligomeric form of the chlorophyll-protein complex of fraction II, whereas fraction III contains specifically oriented and space-fixed molecules of carotenoids.About:

Carotenoids in photosynthesis. I: Location in photosynthetic membranes and light-harvesting function
Journal ArticleDOI
Trimeric forms of the photosystem I reaction center complex pre-exist in the membranes of the cyanobacterium Spirulina platensis.
TL;DR: The trimeric PSI complexes exist and dominate in the Spirulina membranes because the 77K circular dichroism spectrum of the trimeric form is much more similar to that of Spiruline membranes than the spectrum ofThe monomer.

Structure and function of intact photosystem 1 monomers from the cyanobacterium Thermosynechococcus elongatus.
Eithar El-Mohsnawy,Marta J. Kopczak,Eberhard Schlodder,Marc M. Nowaczyk,Helmut E. Meyer,Bettina Warscheid,Navassard V. Karapetyan,Matthias Rögner +7 more
TL;DR: The dynamic equilibrium between monomers and trimers in the thylakoid membrane may indicate a transient monomer population in the course of biogenesis and could also be the basis for short-term adaptation of the cell to changing environmental conditions.

Does the trimeric form of the Photosystem 1 reaction center of cyanobacteria in vivo exist
J. Hladík,D. Sofrová +1 more
TL;DR: Arguments for the existence of the trimeric form of Photosystem 1 in cyanobacterial thylakoid membranes are presented and the question must be answered, which of the stable photosystem 1 forms is the functional form in vivo-monomeric or trimeric?
Journal ArticleDOI
Interactions between cholorophyllase, chlorophyll a, plant lipids and Mg2+
TL;DR: Evidence is presented that small quantitaties of these and other lipids may stabilize the enzyme conformation, and it is suggested that the positive effect that cations have on the enzyme reaction is due to their interaction with the headgroups of chlorophyllase-associated lipids.

TL;DR: It was concluded that Subunit III mediates reduction of P,,,+ by plastocyanin in Photosystem I and suggested that a unit of about 20 chlorophyll a molecules is specifically associated with the reaction center protein 02, = 70,000) in the vicinity of PToO.

Structure of a bacteriochlorophyll a-protein from the green photosynthetic bacterium Prosthecochloris aestuarii.
TL;DR: The three-dimensional structure of a water-soluble bacteriochlorophyll a -containing protein from the green photosynthetic bacterium Prosthecochloris aestuarii has been determined by X-ray crystallography from a 2.8 A resolution electron density map based on four isomorphous derivatives.
