Characterization of cytochromes and plastocyanin in the cyanobacterium Synechocystis sp. PCC 6803
… cytochrome c553 and the copper protein plastocyanin, were isolated from this species and specific antibodies were raised to each protein. Using antibodies as probes, the reciprocal accumulation of the two proteins in response to the copper concentration in the medium was characterized. …

ISOLATION OF ELECTRON TRANSPORT COMPONENTS FROM MICROCYSTIS AERUGINOSA AND OSCILLATORIA SP
… systems. In this project, cytochrome c 553, plastocyanin and ferredoxin, all water-soluble components of the cyanobacterial electron transport chain, were isolated and purified from Microcystis aeruginosa. Cytochrome c 553 was purified from Oscillatoria sp. for reasons of comparison. Finally, …

Photosynthetic electron transport in cyanobacteria
… is similarly efficient in the presence of either plastocyanin or cytochrome $c\sb6$ in the cyanobacterium Synechocystis PCC 6803; (2) mutant strains that lack both these electron carriers show 5-8 fold slowed down kinetics, and the results indicate the presence of an alternate carrier; (3) …

Electron spin-lattice relaxation in two heme iron and two blue-copper proteins at liquid helium temperatures
… cupric azurin (P. aeruginosa) and cupric spinach plastocyanin were measured at 9.5 GHz using the pulse-saturation recovery method. Measurements covered a temperature range of 1.4 K to as high as 22 K, with corresponding relaxation rates up to 10$\sp5$/sec. Improvements in the equipment and the …

Analyzing genetic response mechanisms associated with copper homeostasis in Populus trichocarpa using a bioinformatics approach
… copper for more "essential" proteins like plastocyanin or cytochrome-C oxidase. Down-regulation of "unessential" genes is performed by the copper microRNAs miR307, miR398, and miR408. This thesis increases our understanding of copper homeostasis in plants by analyzing the transcriptomic …

Electron spin-lattice relaxation in proteins, model heme complexes and ferricyanide solutions at helium temperatures
… solutions of the blue-copper proteins azurin and plastocyanin, the low-spin iron heme protein cytochrome-c, two (bis)imidazole ferric heme complexes in three different organic solvents and two ferricyanide solutions. Measurements were performed at X-band frequencies and temperatures between 1.4 …

Exploring the Function of Cytochrome c6A
… c6A was shown to be unable to replace c6 (or plastocyanin) functionally in the photosynthetic electron transfer chain (PETC), despite their significant structural homology. Since then only few studies have revealed additional insights about c6A. Thus its function remains unknown, although the …

CHARACTERIZATION OF LOW MOLECULAR WEIGHT C-TYPE CYTOCHROMES IN CYANOBACTERIA AND PLANTS
Cytochrome c6 (Cyt c6) and Plastocyanin (Pc) are two well characterised redox carriers in the thylakoid lumen of cyanobacteria and algae. In cyanobacteria Cyt c6 or Pc shuttles electrons from the Cyt b6f complex to Photosystem I (PSI) or the terminal oxidase, and in plants Pc transfers electrons …

Regulation of electron donation to photosystem 1
… interaction between the electron-donor protein plastocyanin (Pc) and the photosystem 1 (PSI) subunit PsaF. The physiological regulation of this interaction has been a major subject and hence should be kept in mind to understand the purpose of the different papers and studies reported here. In …

Thermo and drought tolerance markers and regulation of heat stress proteins for chickpea (Cicer arietinum L.; Fabaceae) production in NE South Africa
… bisphosphate carboxylase/oxygenase activase, plastocyanin and protoporphyrinogen oxidase shows their potential role in field grown chickpea tolerance to heat stress at flowering growth stage. In conclusion, chlorophyll fluorescence (both Fᵥ/Fₘ and Fq'/Fₘ') and leaf carbohydrates were …
