Most plant lectins are storage proteins and defence proteins when the plant or the seed is assaulted by insects or fungi (Janzen et al. Plant lectins are a unique group of proteins and glycoproteins with potent biological activities.
Lectins are responsible for cell surface sugar recognition in bacteria, animals, and plants. Examples include bacterial toxins; animal receptors that mediate. cellcell interactions, uptake of glycoconjugates, and pathogen neutralization; and plant toxins and mitogens. The structural basis for selective sugar recognition.
