title: Galacturonic acid as the terminal constituent in the R core polysaccharide of proteus R110 (Ra) mutant.
abstract: Terminal non-reducing position of GalUA residue in the R core region of P. mirabilis R110 (Ra)mutant was established by GLC/MS analysis of methylated degraded polysaccharide. This position of GalUA is exceptional as compared with the terminal constituents present in the known structures of R core polysaccharides in Enterobacteriaceae. As it was shown in serological study, GalUA does not play a role of immunodominant in the examined Proteus R core region.
