Abstract

The study of Pseudomonas aeruginosa-II lectin (PA-IIL) complexes with Man derivatives as a recognition factor has been neglected since its monomer is a very weak ligand. Here, the roles of Man oligomers and complexes in PA-IIL carbohydrate-recognition were studied by both enzyme-linked lectinosorbent and inhibition assays. From the results obtained, it is proposed that high density weak -OH conformation as seen in yeast mannan is also an important PA-IIL recognition factor. This finding provides a peculiar concept of the duality of PA-IIL recognition system for lFucα1→ and related complexes and for high density Manα1→ complexes present in polymannosylated target macromolecules.
