Abstract
A 2.1-kb SmaI-EcoRI DNA fragment upstream of the xanA and xanB genes of Xanthomonas campestris pv. campestris carries two ORFs encoding putative proteins with sequence similarities to the α- and β-subunits of 3-oxoacid-CoA transferases. The two ORFs were termed lpsI and lpsJ because strains carrying appropriate mutations showed an autoagglutination phenotype and because lipopolysaccharides of these mutant strains were altered according to silver-stained polyacrylamide gels. The monosaccharide composition of the exopolysaccharide xanthan produced by lpsI and lpsJ mutants remained unchanged.
