The present invention encompasses a novel S. aureus bioconjugate vaccine. More generally, the invention is directed to Gram-positive and other bioconjugate vaccines containing a protein carrier, at least one polysaccharide such as a capsular Gram-positive polysaccharide, and, optionally, an adjuvant or pharmaceutically acceptable carrier. The instant invention also includes methods of producing Gram-positive and other bioconjugate vaccines. An N-glycosylated protein is also provided that contains one or more polysaccharides such as Gram-positive polysaccharides. The invention is additionally directed to engineered prokaryotic organisms comprising nucleotide sequences encoding a glycosyltransferase of a first prokaryotic organism and a glycosyltransferase of a second prokaryotic organism. The invention further includes plasmids and prokaryotic cells transformed with plasmids encoding polysaccharides and enzymes which produce an N-glycosylated protein and/or bioconjugate vaccine. Further, the invention is directed to methods of inducing an immune response in a mammal comprising administering said bioconjugate vaccines.
