Favin, a crystalline lectin from Vicia faba

A lectin from the fava bean (Vicia faba) has been purified and crystallized in a form suitable for high-resolution crystallographic structure analysis. This protein binds glucose- and mannose-like saccharides, and it is mitogenic for lymphocytes. The fava lectin crystallizes in the orthorhombic space group. P212121 with unit cell dimensions a = 90.0, b = 89.3, and c = 67.4 Å. The mass of protein in the asymmetric unit is 53,000 daltons,...
