Organization of chlorophyll-protein complexes of Photosystem I in Chlamydomonas reinhardii
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1983Abstract The polypeptide pattern, chlorophyll-protein complexes, fluorescence emission spectra and light intensity required for saturation of electron flow via Photosystem (PS) II and PS I in a pale-green photoautotrophic mutant, y-lp, were compared to those of the parent strain, Chlamydomonas reinhardii y-1 cells.

Composition of a Photosystem I chlorophyll protein complex from Anabaena flos-aquae
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977The use of Triton X-100 to solubilize membrane fragments from Anabaena flos-aquae in conjunction with DEAE cellulose chromatography allows the separation of three green fractions. Fraction 1 is detergent-solubilized chlorophyll, and Fraction 2 contains one polypeptide in the 15 kdalton area.

1. Greening barley and pea leaves treated with lincomycin have a reduced chlorophyll content. Lincomycin dose not alter the proportion of chlorophyll in chlorophyll-protein complex II (CPII) but greatly reduces that in chlorophyll-protein complex I (CPI). 2.

The light-harvesting complex of photosystem I (LHCI) was isolated from wild-type cells of Chlamydomonas reinhardtii; the Chl a/b-protein complex contains four major polypeptides of approximately 27, 26, 24, and 20 kDa (polypeptides 14, 15, 17.2, and 22, respectively, in the nomenclature for Chlamydomonas thylakoid proteins).

The stability of chlorophyll-protein complexes of photosystem I (PSI) and photosystem II (PSII) was investigated by chlorophyll (Chl) fluorescence spectroscopy, absorption spectra and native green gel separation system during flag leaf senescence of two rice varieties (IIyou 129 and Shanyou 63) grown under outdoor conditions.

Properties are studied of pterin-protein complex (PPC), possible precursor of ferredoxin in electrone transport chain PS-I. PPC is shown to form chelate complex with Fe ions which are capable to activate the process of light reduction of NADP+ by chloroplasts in the absence of ferrodoxin.

Changes in the protein secondary structure and electron transport activity of the Triton X-100-treated photosystem I (PSI) and photosystem II (PSII) complexes after strong illumination treatment were studied using Fourier transform-infrared (FT-IR) spectroscopy and an oxygen electrode. Short periods of photoinhibitory treatment led to obvious decreases

Chlorophyll-protein complexes associated with photosystem I were isolated from native photosystem I particles (PS 1-200) of spinach thylakoids by centrifugation in SDS-sucrose density gradients. These complexes were designated CPIa (Chl/P700 ratio of =160), CPI' (CW/P700 ratio of =70), and LHCI (light-harvesting Chi a/bprotein complex associated with ...

Photosynthetic structures when imaged with nonlinear optical microscopy give rise to high third harmonic generation (THG) signal intensity due to the presence of chlorophylls and xanthophylls which have large second hyperpolarizabilitiy (γ) values. The γ value of trimers of the light-harvesting chlorophyll a/b pigment-protein complex of photosystem II (

[Study of electron transfer in pigment-protein complexes of photosystem I].
Molekuliarnaia biologiia, 1979The electron transfer processes occuring in SDS chlorophyll--protein complexes of photosystem I were studied by flash photolysis. Transient species with lifetime about 5.10(-5) sec were found to be produced on flash excitation of complex buffer solutions.
