A Complex Gene Encoding a Dinoflagellate Light-Harvesting Protein

1998
Most of the chlorophyll in eukaryotic organisms is bound to intrinsic light-harvesting complexes. Although these complexes have apoproteins of widely differing Mr (17–30kDa) and bind almost the entire range of photosynthetic pigments, they are evolutionarily related [1].

Identification of a novel light-harvesting complex II protein (LHC IIc?)

Photosynthesis Research, 1994
The caroteno-chlorophyll-protein, LHC IIc, is a relatively minor component of the PS II antenna. Isolated LHC IIc contains a major protein of 28 kDa along with a 26 kDa subunit in lower abundance. Previously, it was not known if the 26 kDa protein was closely related to the 28 kDa LHC IIc protein or if it was a comigrating LHC IIb contaminating subunit.

Monoclonal Antibodies to the Light Harvesting Chlorophyll-Protein Complex

1987
The light harvesting chlorophyll a/b protein complex binds antenna pigments which serve to transfer absorbed light energy to photosystem II for use in photosynthesis. Recently LHC-II has been the subject of much research aimed at determining its structure and function in the regulation of exciton distribution between the photosystems and cation ...

Evolutionary distribution of light-harvesting complex-like proteins in photosynthetic eukaryotes

Genome, 2010
Light-harvesting-like (LIL) proteins are low-molecular-mass membrane proteins related to the light-harvesting complexes, which form the dominant antenna system in most photosynthetic eukaryotes. To analyze the LIL protein family, we mined a number of publicly available databases to identify members of this family in a broad range of organisms.

The PucC protein of Rhodobacter capsulatus mitigates an inhibitory effect of light-harvesting 2 α and β proteins on light-harvesting complex 1

Photosynthesis Research, 2007
Rhodobacter capsulatus contains lhaA and pucC genes that have been implicated in light-harvesting complex 1 and 2 (LH1 and LH2) assembly. The proteins encoded by these genes, and homologues in other photosynthetic organisms, have been classified as the bacteriochlorophyll delivery (BCD) family of the major facilitator superfamily.

Evidence for a dimer of the light-harvesting chlorophyll-protein complex II

Plant Science Letters, 1974
Abstract Polyacrylamide gel electrophoresis of sodium dodecyl-benzene sulphonate (SDBS) solubilised chloroplast lamellae results initially in 4 major chlorophyll-containing bands. After standing only 3 major bands are obtained. The unstable band is a dimer of pigment-protein complex II which dissociates to the monomer.

Pigment-Protein Complexes and Light Harvesting in Eustigmatophyte Algae

1987
The Eustigmatophyta comprises a small group of yellow-green coccoid unicellular algae (1) with unique array of pigments, notable primarily for the absence of Chi b and Chl c; the major pigments are Chl a, β-carotene, violaxanthin and vaucheriaxanthin ester.

Light-Harvesting Complexes of Diatoms: Fucoxanthin-Chlorophyll Proteins

2020
Diatoms contain antenna proteins called fucoxanthin-chlorophyll-proteins (FCP) that belong to the huge family of intrinsic light-harvesting complex proteins (LHCs). In comparison to higher plants, many more polypeptides are present, that are sorted into three major groups: Lhcf that constitute all major antenna complexes, Lhcr that are only found ...

Pigment and protein composition of reconstituted light-harvesting complexes and effects of some protein modifications

Photosynthesis Research, 1992
The structure and heterogeneity of LHC II were studied by in vitro reconstitution of apoproteins with pigments (Plumley and Schmidt 1987, Proc Natl Acad Sci 84: 146-150). Reconstituted CP 2 complexes purified by LDS-PAGE were subsequently characterized and shown to have spectroscopic properties and pigment-protein compositions and stoichiometries ...

Chlorophyll a/b-Proteins in Their Relation to the Light-Harvesting Complex

1984
In 1966 two research groups (Ogawa et al. 1966; Thornber et al. 1966) were the first to demonstrate that sodium do-decyl sulfate dissociated thylakoid membranes can be separated into three different zones two of which represent chlorophyll-proteins.
