摘要：

Carbohydrates were characterized in the human placental alpha-2-macroglobulin receptor and its associated protein. Carbohydrates, largely N-linked, contributed to about 18% of the size of the receptor alpha-chain and to about 25% of the beta-chain. The 40 kDa receptor-associated protein also contained carbohydrate. The alpha- and beta-chains contained a wide variety of carbohydrates as judged by binding of lectins. Monosaccharide-competing inhibition of alpha-2M-methylamine binding by WGA suggested a functional significance of sugars in binding of ligands to the alpha-chain.
