The structure of a phytohemagglutinin receptor site from human erythrocytes.
A highly purified glycopeptide with potent phytohemagglutinin (PHA) receptor site activity has been isolated from human erythrocyte membranes. The glycopeptide was released from the membranes by trypsin, treated with alkaline borohydride, and purified by repeated gel filtration, further proteolytic digestion with Pronase, and diethylaminoethyl cellulose chromatography. It has a molecular weight...
متن کاملSolubilization and partial characterization of a phytohemagglutinin receptor site from human erythrocytes.
Trypsin treatment of human erythrocytes releases a soluble glycopeptide which binds to phytohemagglutinin and abolishes the erythroagglutinating and lymphocyte-stimulating properties of this molecule. The glycopeptide has been purified by alkaline borohydride treatment, proteolytic digestion, gel filtration, and DEAE-cellulose chromatography. The most highly purified glycopeptide has a molecula...
متن کاملTHE ISOLATION OF ENZYME TRANSKETOLASE FROM HUMAN ERYTHROCYTES: THE CHARACTERIZATION OF ITS QUARTERNARY STRUCTURE
Human erythrocyte transketolase (sedoheptulose-7-phosphate: D-glyceraldehyde-3-phosphate, glycolaldehyde transferase, E.C. 2.2.1.1.) has been isolated from erythrocytes with a specific activity of 59.84 U/mg. SDS-PAGE and SE-HPLC were used both as a measure of purity and as a preparative mean to obtain a higher degree of purity. Four protein bands corresponding to molecular weights of 32,0...
متن کاملfrom linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
