概要

To obtain information about the characteristics offish mucus glycoproteins, glycopeptides were separated from the Pronase digests of the external mucous materials of 13 species of fishes and analyzed for their cazbohydrate components. The involvement of N-acetylgalactosamine in the carbohydrate-peptide linkage was also investigated. The carbohydrate compositions of the gly-copeptides were very diverse depending on fish species. Glycopeptides from butterfly ray, spiny rasp skate, slimy and finespotted flounder did not contain sialic acid, while those from the other fishes contained a large amount of this acidic sugar. The glycopeptide from butterfly ray was sulfated. A part of the N-acetylgalactosamine which was found in all the glycopeptides was in-volved in the carbohydrate-peptide linkage.
