CRYSTAL STRUCTURE OF DIOCLEA GUIANENSIS SEED LECTIN
Overview
Diocleinae legume lectins are a group of oligomeric proteins whose, subunits display a high degree of primary structure and tertiary fold, conservation but exhibit considerable diversity in their oligomerisation, modes. To elucidate the structural determinants underlaying Diocleinae, lectin oligomerisation, we have determined the crystal structures of, native and cadmium-substituted Dioclea guianensis (Dguia) seed lectin., These structures have been solved by molecular replacement using, concanavalin (ConA) coordinates as the starting model, and refined against, data to 2.0 A resolution. In the native (Mn/Ca-Dguia) crystal form, (P4(3)2(1)2), the asymmetric unit contains two monomers arranged into a, canonical legume lectin dimer, and the tetramer is formed with a, symmetry-related dimer. ...
