ENZYMATIC SYNTHESIS OF THE SALMONELLA 0-ANTIGEN

Abstract
Enzymatic synthesis of the galactosyl-mannosyl-rhamnosyl repeating unit of the Salmonella anatum O-antigen from nucleotide sugar precursors is described. Long chains are formed with little or no terminal labeling of the lipopolysaccharide. The product is largely precipitable by anti-O-antiserum and gives rise to the typical oligosaccharide pattern of the antigen following partial acid hydrolysis.
