A classification of nucleotide-diphospho-sugar glycosyltransferases based on amino acid sequence similarities

The authors have informed us that, in the above paper, several polypeptide GalNAc transferases were listed as part of family 2, i.e. a family of inverting enzymes. However, these enzymes transfer GalNAc from UDP-GalNAc to Ser or Thr residues forming an linkage. They are therefore retaining enzymes a... View More
