Peptide−Sugar Ligation Catalyzed by Transpeptidase Sortase: A Facile Approach to Neoglycoconjugate Synthesis
摘要:
Glycoconjugate synthesis involving sugar and polypeptide remains a formidable challenge. Here we report a novel enzymatic method involving an unprecedented sortase-catalyzed transamidation reaction for site-specific engineering of sugars into native proteins. We show that sugars appended with a 6-aminohexose moiety can be efficiently ligated to peptides; and proteins encoded with a LPXTG sortase, recognition sequence. This robust reaction provides an elegant and simple approach for generating neoglycoproteins with an amide-linked sugar moiety at the carboxy terminus.

The present invention relates to fucose- and mannose-derived glycomimetics and their general use in prophylaxis or treatment of Pseudomonas aeruginosa infections including respiratory tract infections, urinary tract infections, nosocomial infections and chronic wound infections in a patient encompassing a patient suffering already from cystic fibrosis. Said glycomimetics are inhibitors of Pseudomonas aeruginosa lectin LecB.
