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-...
متن کاملA Spectrophotometric Study of the Carbohydrate Binding Site of Concanavalin A*
The carbohydrate binding sites of the jack bean lectin, concanavalin A, were studied spectrophotometrically. A number of ligands were examined for their ability to displace the chromogenic ligand p-nitrophenyl cr-n-mannopyranoside. It is shown that this technique provides a simple and convenient approach for obtaining association constants for a series of displacing ligands. The data can best b...
متن کاملSerum concanavalin-A binding in rheumatoid arthritis.
A nephelometric assay of concanavalin-A binding of serum acute phase proteins (con-A binding) has been used in cross-sectional and sequential studies of disease activity in rheumatoid arthritis (RA). Con-A binding correlated well with blood viscosity, C-reactive protein, and other individual acute phase reactants in patients with active RA. Twenty-four patients were treated for 6 months with D-...
متن کاملFluorescently labeled ribosomes as a tool for analyzing antibiotic binding.
Measuring the binding of antibiotics and other small-molecular-weight ligands to the 2.5 MDa ribosome often presents formidable challenges. Here, we describe a general method for studying binding of ligands to ribosomes that carry a site-specific fluorescent label covalently attached to one of the ribosomal proteins. As a proof of principle, an environment-sensitive fluorescent group was placed...
