Interestingly, these lectins are the most prominent proteins in the tuber tissue. Lectins with similar properties were isolated from the Araceae species Colocasia esculenta, Xanthostoma sagittifolium and Diffenbachia sequina. Lectin activity has also been reported in the Araceae species Alocasia, Armorphophallus, Ariseama, Gonatanthus, Pothos, Remusatia, Richardia, Sauromatum and Scindapsus. See: Lectins Biol. Bichem. Clin. Biochem. 1990 (7); 19-26
Arum lectin aggltuinates rabbit but not human erythrocytes. See: Plant Physiol. 1995 (107); 1147-1158
It is specifically inhibited by N-acetyllactosamine (Gal beta 1,4GlcNAc), but is not significantly inhibited by monosaccharides or by lactose (Gal beta 1,4Glc), lacto-N-biose 1 (Gal beta 1,3GlcNAc), or chitobiose (GlcNAc beta 1,4GlcNAc).
