Production of fruiting-body lectins of Pleurotus cornucopiae in methylotrophic yeast Pichia pastoris

Fruiting-body lectin genes obtained from Pleurotus cornucopiae were expressed in Pichia pastoris Because of glycosylation of the products, their molecular mass was larger than that of the corresponding native lectins. They showed binding activity to porcine stomach mucin in the enzyme-linked lectin assay system, but did not agglutinate red blood cells.
