Cleavage of phycocyanobilin from C-phycocyanin.
The chromophore of C-phycocyanin, phycocyanobilin, was cleaved from the protein with methanol, concentrated hydrochloric acid, or subtilisin BPN’. The pigments obtained were converted to their dimethyl esters and purified by preparative high pressure liquid chromatography and examined for purity by analytical high pressure liquid chromatography on silica gel. They were characterized by proton t...
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 کاملStructure Based Computational Analysis and Molecular Phylogeny of C- Phycocyanin Gene from the Selected Cyanobacteria
Cyanobacteria play a vital role in the production of phycobiliproteins that includes phycocyanin and phycoerythrin pigments. Phycocyanin and related phycobiliproteins have wide variety of application that is used in the food, biotechnology and cosmetic industry because of their color, fluorescent and antioxidant properties. The present study is focused to understand the pigment at molecular lev...
متن کاملMonomer molecular weight of T antigen from simian virus 40-infected and transformed cells.
T-antigens from simian virus 40 (SV 40)-transformed and lytically infected cells have been isolated by immunoprecipitation and their molecular weights estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. T-antigen from SV40-transformed mouse and hamster cells has an apparent molecular weight of 94,000 whereas that from several lines of SV40-infected monkey cells is 84,000. In...
متن کاملSynthesis and characterization of dimethacrylate monomer with high molecular weight for root canal filling materials.
A new dimethacrylate monomer 9,9'-bis[4-(2'-hydroxy-3'-methacryloyloxy-propoxy)phenyl] fluorene (3) with a molecular weight of 634 was synthesized in 51.4% yield by addition of a glycidyl ether group to 9,9'-bis(4-hydroxyphenyl) fluorene (1) by the reaction of compound 1 with epichlorohydrin, and then introducing the methacrylate moiety by the reaction of the epoxy group with methacrylic acid. ...
