Characterization of R-phycocyanin. Chromophore content of R-phycocyanin and C-phycoerythrin.
R-phycocyanin was purified from two independent isolates of the unicellular red alga Porphyridium cruentum. At pH 7.0 the protein sediments as a single component with s 20,w of 5.98 S (at 2 mg/ml, gamma/2=0.02). Over a protein concentration range of 0.2 to 0.5 mg/ml (gamma/2=0.16), sedimentation equilibrium gave a molecular weight of 103,000 +/- 6,000 with no evidence of heterogeneity. In commo...
متن کاملChromophores of allophycocyanin and R-phycocyanin.
The biliprotein allophycocyanin was purified from Phormidium luridum, Anabaena variabilis and Plectonema boryanum. R-phycocyanin was purified from Rhodymenia palmata. The chromophores were cleaved from the denatured protein by methanol hydrolysis. They were purified and crystallized as the dimethyl esters. Chromatographic and absorption-spectral (visible-ultraviolet and infrared) comparisons wi...
متن کاملCrystal structure of R-phycocyanin and possible energy transfer pathways in the phycobilisome.
The crystal structure of R-phycocyanin from Polysiphonia urceolata (R-PC-PU) at 2.4 A is reported. The R-PC-PU crystal belongs to space group P4(3)2(1)2 with cell parameters a = 135.1 A, c = 210.0 A, and alpha = beta = gamma = 90 degrees. The structure was determined by molecular replacement. The crystallographic R-factor of the refined model is 0.189 (R(free) = 0.239). Comparison of the microe...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
