This study examined the physicochemical interactions between vesicles formed by phosphatidylcholine (PC) and glycosylated polymeric amphiphile N-acetyl-β-d-glucosaminyl-PEG900-docosanate (C22PEG900GlcNAc) conjugated with Bauhinia variegata lectin (BVL). Lectins are proteins or glycoproteins capable

A chimeric lectin formed from Bauhinia purpurea lectin and Lens culinaris lectin recognizes a unique carbohydrate structure.

To determine the carbohydrate-binding site of Bauhinia purpurea lectin (BPA), a D-galactose- and lactose-binding lectin, a peptide which interacts with lactose was purified from endoproteinase Asp-N digests of BPA by chromatography on a lactose-Sepharose column. It consists of nine amino acids and

Carbohydrate-binding specificities of five lectins that bind to O-Glycosyl-linked carbohydrate chains. Quantitative analysis by frontal-affinity chromatography.

Carbohydrate-derivatized self-assembled monolayers (SAMs) are used as a model system to address issues involving cell-surface carbohydrate-protein interactions. Here we examine the influence of carbohydrate surface density on protein-binding avidity. We show that the binding selectivity of Bauhinia

A chimeric lectin gene was constructed by using a cDNA clone coding the Bauhinia purpurea lectin (BPA) in which a part of the metal-binding region was replaced by the corresponding region of the mannose-binding Lens culinaris lectin (LCA). The chimeric lectin expressed in Escherichia coli was found
