title: Chemoenzymatic synthesis of high-mannose type HIV-1 gp120 glycopeptides.
abstract: A chemoenzymatic approach to the synthesis of glycoforms of HIV-1 gp120 glycopeptides is described. Thus, the high-mannose type glycopeptides [gp120 (336-342)] containing Man(9), Man(6) and Man(5) moieties, respectively, were synthesized in satisfactory yields via transglycosylation to the acetylglucosaminyl peptide, using the recombinant Arthrobacter Endo-beta-N-acetyl-glucosaminidase (Endo-A) as the key enzyme.
