Properties and Ultrastructure of Phycoerythrin From Porphyridium cruentum " 2
Phycoerythrin, a photosynthetic accessory pigment, was isolated from Porphyridium cruentum and examined by eleotron microscopy and disc gel electrophoresis. The absorption monomer, with maxima at 563, 545, and a shoulder at 500 nm, has a molecular weight of about 300,000. With phosphatungstic acid staining it appears as a tightly structured disc-shaped particle possessing a mean diameter of 101...

متن کاملPhycoerythrin Signatures in the Littoral Zone
I am interested in understanding how, and in what ways, the taxonomic composition of the phytoplankton affects ecosystem-level processes in the sea. I am particularly interested in the relationship between the optical environment and the distribution of phytoplankton with different light harvesting pigments. To this end, I have been working in collaboration with experts in remote sensing and oc...
متن کاملCharacterization 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 کاملChromophore content of C-phycoerythrin from various Cyanobacteria.
The molar extinction coefficient for phycoerythrobilin (l a) was calculated by two independent methods. It is different from that of the cleaved chromophore, phycobiliviolin (2). By unfolding with urea or tryptic digestion, the chromophore absorption of C-phycoerythrin (PE) was determined free of any protein influence. The chromophore content of PE from various Cyanobacteria was determined with...
