Effect of linocmycin on the chlorophyll protein complex I content and photosystem I activity of greening leaves.

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1977
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.

Photosystem I and II chlorophyll-protein complexes of higher plant chloroplasts

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract An improved purification procedure which provides large quantities of the Photosystem I and II chlorophyll-protein complexes in a homogeneous form is reported. Only approx. 20% of the chlorophyll in the plants examined is associated with Photosystem I. Preliminary analyses of the properties of the two chlorophyll-proteins are given.

Chlorophyll—protein complexes related to photosystem I in Chlamydomonas reinhardtii

Journal of Photochemistry and Photobiology B: Biology, 1989
Abstract A study of the photosystem I (PS I)-related chlorophyll (Chl)—protein complexes of the unicellular green alga Chlamydomonas reinhardtii was performed, using the wild type and six photosynthesis mutants. Three complexes have been previously described in the literature: CP Ia, undissociated PS I complex; CP 0, Chl a + b peripheral ...

Chlorophyll Composition in an Isolated Chlorophyll a‐Protein Complex of Photosystem I

Physiologia Plantarum, 1979
AbstractA P700‐chlorophyll a‐protein complex, solubilized by the detergent Triton X‐100, has been isolated by hydroxyl apatite column chromatography. The chlorophyll composition was determined by thin‐layer chromatography and spectrofluorimetric analysis. This photosystem I reaction centre complex, prepared at pH 7, contained pheophytin a and P700 in a

Organization of chlorophyll-protein complexes of Photosystem I in Chlamydomonas reinhardii

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1983
Abstract 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.

Pentatricopeptide repeat protein PHOTOSYSTEM I BIOGENESIS FACTOR2 is required for splicing of ycf3.

Journal of Integrative Plant Biology, 2020
To gain a better understanding of the molecular mechanisms of photosystem I (PSI) biogenesis, we characterized the Arabidopsis thaliana photosystem I biogenesis factor 2 (pbf2) mutant, which lacks PSI complex.

Chlorophyll antenna proteins of photosystem I: Topology, synthesis, and regulation of the 20-kDa subunit of Chlamydomonas light-harvesting complex of photosystem I

Archives of Biochemistry and Biophysics, 1987
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).

Differential changes in degradation of chlorophyll–protein complexes of photosystem I and photosystem II during flag leaf senescence of rice

Plant Physiology and Biochemistry, 2005
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.

Strong-Light Photoinhibition Treatment Accelerates the Changes of Protein Secondary Structures in Triton-Treated Photosystem I and Photosystem II Complexes

Journal of Protein Chemistry, 2001
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
