This lectin is a dimer of two identical subunits of about 36,000 daltons each with an isoelectric point of about pH 9. Unlike Ulex europaeus and Lotus tetragonolobus lectins which prefer (a -1,2) linked fucose residues, Aleuria aurantia lectin binds preferentially to fucose linked (a -1,6) to N-acetylglucosamine or to fucose linked (a -1,3) to N-acetyllactosamine related structures. |
