Function

[LEC_LEUMI] Binds preferentially to oligosaccharides bearing the sequence Man-alpha-1->2 Man-alpha-1->6 Man-alpha-1->6Man found in early steps of glycoprotein processing in the endoplasmic reticulum. It binds weakly to highly processed oligosaccharide structures.^[1]

Publication Abstract from PubMed

The crystal structure of the seed lectin from the tropical legume Bowringia milbraedii was determined in complex with the disaccharide ligand Man(alpha1-2)Man. In solution, the protein exhibits a dynamic dimer-tetramer equilibrium, consistent with the concanavalin A-type tetramer observed in the crystal. Contacts between the tetramers are mediated almost exclusively through the carbohydrate ligand, resulting in a crystal lattice virtually identical to that of the concanavalin-A:Man(alpha1-2)Man complex, even though both proteins have less than 50% sequence identity. The disaccharide binds exclusively in a "downstream" binding mode, with the non-reducing mannose occupying the monosaccharide-binding site. The reducing mannose is bound in a predominantly polar subsite involving Tyr131, Gln218, and Tyr219.
