| Description | Peanut agglutinin is a 110,000 molecular weight lectin composed of four identical subunits of approximately 27,000D each. PNA binds preferentially to a commonly occurring structure, galactosyl (b-1,3) N-acetylgalactosamine. This carbohydrate sequence (called the ``T-antigen'') is present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). In fact, even sialic acid which is not bound directly to the receptor sugars may inhibit binding. Although PNA appears not to require any divalent cations for activity, the presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence. PNA is useful in distinguishing between nor |
