CATALYTIC DOMAINS OF β/1,4)-GALACTOSYLTRANSFERASE I HAVING ALTERED DONOR AND ACCEPTOR SPECIFICITIES, DOMAINS THAT PROMOTE IN VITRO PROTEIN FOLDING, AND METHODS FOR THEIR USE
Disclosed are methods and compositions that can be used to synthesize oligosaccharides; mutants of galactosyltransferases having altered donor and acceptor specificity; methods for increasing the immunogenicity of an antigen; and polypeptide stem regions that can be used to promote in vitro folding of polypeptides, such as the catalytic domain from a galactosyltransferase.
