Interaction of 24 different seed lectins/ isolectins from the Leguminosae with muramic acid (MurAc), N‐acetylmuramic acid (MurNAc) and muramyl‐dipeptides (MDP), was studied by hapten‐inhibition of haemagglutination. Although many lectins were shown to interact, irrespective of their monosaccharide‐specificity or systematic position, glucose/mannose‐specific lectins from the tribe Vicieae exhibited the best affinity for these components of the bacterial cell wall. The discrepancies observed in the binding of the muramyl‐dipeptide diastereo‐isomers to lectins suggest that the binding is somewhat conformation‐dependent. These interactions could be possibly involved in the recognition of bacteria by plants.
