Concanavalin A Product Information

Source: Jack Bean (Canavalia ensiformis)

Concanavalin A is a member of a group of proteins called lectins which are proteins that react with specific sugar residues. The conformation of concanavalin is pH-dependent At pH 4.5-5.6 it exists as a dimer, above pH 7 it is predominantly tetrameric. Concanavalin A binds two metal ions per monomer: a transition metal at site S1 and Ca2+ at site S2. Both ions must be present for saccharide binding. Concanavalin A reacts with non-reducing α-D-Glucose and α-D-mannose. The molecular weight is 104 kDa and the pI is 4.5-5.5.
