13C-NMR spectral study of reductively [13C]methylated glycophorin B. 1984

R D Carter, and J R Brooks, and K Dill

Glycophorin BN was reductively [13C]methylated and the 13C chemical shift of the N-terminal [13C]dimethyl-leucine residue was monitored as a function of pH. These results were compared to the pH-dependent chemical shift studies of the N-terminal [13C]dimethylleucine residues of intact glycophorin AN and N-terminal glyco-octapeptide AN. The results indicate that the titration data for [13C]dimethylleucine of glycophorin BN more closely resembles the titration data observed for the [13C]dimethylleucine residue of the N-terminal glyco-octapeptide AN rather than for the [13C]dimethylleucine residue of intact glycophorin AN. Integration of the 13C resonances indicated that glycophorin BN contains 3-4 lysine residues.

UI MeSH Term Description Entries
D008745 Methylation Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed) Methylations
D008951 MNSs Blood-Group System A system of universal human blood group isoantigens with many associated subgroups. The M and N traits are codominant and the S and s traits are probably very closely linked alleles, including the U antigen. This system is most frequently used in paternity studies.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D006021 Glycophorins The major sialoglycoprotein of human erythrocyte membranes. It consists of at least two sialoglycopeptides and is composed of 60% carbohydrate including sialic acid and 40% protein. It is involved in a number of different biological activities including the binding of MN blood groups, influenza viruses, kidney bean phytohemagglutinin, and wheat germ agglutinin.
