BINDING SITES ON CONCANAVALIN A 399 Concanavalin
Equilibrium dialysis of concanavalin A against methyl c¢-D-mannopyranoside and methyl C¢-D-glucopyranoside conducted at 2 ° in the presence of I M NaC1 showed that concanavalin A is bivalent. A SCATCHARD plot of the data obtained gave straight lines for both sugars with observed association constants (K') of 1. 4. lO 4 1/mole for methyl ,¢-D-mannopyranoside and o.3" IO 4 1/mole for methyl ~¢-D-...

Monovalent derivatives of concanavalin A.
Monovalent dimers of concanavalin A (Con A) have been prepared by a combination of succinylation and photoaffinity labeling. Partial derivatization of native Con A using the photoaffinity label, p-azidophenyl-alpha-D-mannopyranoside, followed by affinity chromatography yielded a fraction that consisted of dimers with a single saccharide-binding site at pH 5. These monovalent dimers formed dival...
متن کاملEffect of concanavalin A dose, unbound concanavalin A, temperature, Ca2+ and Mg2+, and vinblastine on capping of concanavalin A receptors of human peripheral blood lymphocytes.
The capping of Concanavalin A (Con A) receptors induced by Con A was studied using human peripheral blood lymphocytes. The effects of Con A dose (5--100 micrograms/ml), pretreatment at 4 degrees C, unbound Con A, extracellular Ca2+ and Mg2+ and vinblastine were evaluated using Con A-horseradish peroxidase and electron microscopy. Lymphocytes incubated with Con A at 4 degrees C and fixed with gl...
متن کاملGalactosyltransferase and concanavalin A agglutination of cells.
A correlation has been observed between concanavalin A agglutination of various cell types and the presence of surface membrane galactosyltransferase (1-O-alpha-D-Galactosyl-myo-inositol:raffinose galactosyltransferase, EC 2.4.1.67) activity. Moreover, a reduction to less than 50% of cell surface galactosyltransferase activity occurred after treatment with concanavalin A; other cell surface gly...
