Glycosylation of proteins is an essential process in all eukaryotes and a great diversity in
types of protein glycosylation exists in animals, plants and microorganisms. Mucin-type O …

Mucin-type linkages (GalNAcα1-O-Ser/Thr) are initiated by a family of glycosyltransferases
known as the UDP-N-acetylgalactosamine: polypeptide N-acetylgalactosaminyltransferases …

O-GalNAc-glycosylation is one of the main types of glycosylation in mammalian cells. No
consensus recognition sequence for the O-glycosyltransferases is known, making prediction …

The specificities of the UDP-GalNAc: polypeptide N-acetylgalactosaminyltransferases which
link the carbohydrate GalNAc to the side-chain of certain serine and threonine residues in …

BACKGROUND: Posttranslational modifications (PTMs) greatly expand the function and
regulation of proteins, and glycosylation is the most abundant and diverse PTM. Of the many …

Mucin-type O-glycans are found on mucins as well as many other glycoproteins. The
initiation step in synthesis is catalyzed by a large family of polypeptide GalNAc-transferases …

Mucin-type O-glycosylation is initiated by UDP-N-acetylgalactosamine: polypeptideN-
acetylgalactosaminyltransferases (GalNAc-transferases). The role each GalNAc-transferase …

Mucin glycoproteins are major constituents of the glycocalyx that covers mucosal epithelium.
Two broad classes of mucins exist: membrane-associated and secretory. Of the secreted …

O-GLYCBASE is a database of glycoproteins with O-linked glycosylation sites. entries with at
least one experimentally verified O-glycosylation site have been compiled from protein …

A UDP-GalNAc: polypeptide N-acetylgalactosaminyltransferase (GalNAc-transferase) from
human placenta was purified to apparent homogeneity using a synthetic acceptor peptide as …
