Function

CONA_CANBR Glucose/D-mannose specific lectin. Has anti-inflammatory activity in rats. Induces histamine release in mast cells from hamster and rat. Induces lymphocyte proliferation and IFNG production. Shows toxicity against the aquatic snail B.glabrata at concentrations higher than 20 ug/ml.[1] [2] [3] [4] [5] [6] [7]

Publication Abstract from PubMed

The structure of concanavalin A (ConA) has been studied intensively due to its specific interactions with carbohydrates and its heterometal (Ca2+ and Mn2+) coordination. Most structures from X-ray crystallography have shown ConA as a dimer or tetramer, because the complex formation requires specific crystallization conditions. Here, we reported a monomeric structure of ConA with a resolution of 1.6 A, which revealed that metal coordination could trigger sugar binding ability. The calcium coordination residue, Asn14, changes the orientation of carbohydrate binding residues and biophysical details, including structural information, providing valuable clues for the development and application of detection kits using ConA.
