  • Method for glycosylating hydroxylysine residues in polypeptides or peptides
    Patent number: 7951562
    Abstract: This invention relates to a multifunctional enzyme having lysyl hydroxylase and glycosyltransferase activity and to the use of the enzyme in glycosylating hydroxylysine residues. In particular this invention relates to a method for producing glycosyltransferase activity, which comprises that a nucleotide sequence encoding lysyl hydroxylase and glycosyltransferase activity is introduced and expressed in a chosen host and the protein product is recovered from the host cell or from the culture medium.
    Type: Grant
    Filed: October 31, 2007
    Date of Patent: May 31, 2011
    Assignee: Oulun Yliopisto
    Inventors: Raili Myllyla, Jari Heikkinen, Maija Risteli, Chunguang Wang
