质量标准 Product Description
CAS Number: 11028-71-0
Molecular Weight: The monomeric molecular weight is 25.5 kDa. At pH 5.5 Con A exists as a dimer and at pH>7 it exists as a tetramer.1 Extinction Coefficient: E1% = 11.4 (280 nm, 100 mM NaCl)2 pI: 4.5, 4.7, 5.1, 5.53 Synonyms: Con A, Concanavalin A from Jack bean
Concanavalin A isolated from Jack bean is a lectin, although it is not a glycoprotein like most other phytohemagglutinins.4 The protein does not contain any cysteine residues.5 Con A is a metalloprotein and requires a transition metal ions such as manganese and calcium for saccharide binding to occur. Each subunit has a binding site for one Mn2+, one Ca2+, and one oligo- or polysaccharide. Removal of these cations by dialysis under acidic conditions abolishes
the carbohydrate binding activity. This protein will bind to the glucosyl and mannosyl residues at the nonreducing terminus of polysaccharides and glycoproteins. Unmodified hydroxyl groups at the C3, C4, and C6 positions of D-glucopyranosyl or D-mannopyranosyl rings are considered to be essential for binding. α-glucopyranosides and α-mannopyranosides bind more strongly than the β-forms. 6
