The block mechanism of O-specific polysaccharides biosynthesis was demonstrated for Salmonella nitra (serogroup A) and S. haifa (serogroup B). Due to the moderate specificity of glycosyl transferases from S. nitra, S. typhimurium, S. haifa and S. kentucky (serogroup C3) towards the 3,6-dideoxyhexose structure a paratose residue can be incorporated into the polysaccharide chain instead of an abequose residue, and vice versa.
