title: Mucin (qniumucin), a glycoprotein from jellyfish, and determination of its main chain structure.
abstract: We extracted a novel glycoprotein, a member of the mucin family, from five species of jellyfish with high yields (1%-3% dry weight, 0.02%-0.1% wet weight) and determined its main chain structure and molecular mass. The glycoprotein contains unique tandem repeats of eight amino acids, of which two threonine residues are probably glycosylated by N-acetyl-d-galactosamine (GalNAc). We named this substance, which is common in jellyfish and similar to the human mucin MUC5AC, "qniumucin" and suggested the utilization of this compound as a new marine resource.
