In this paper we present the structure and describe serological properties of the O-specific polysaccharide of Proteus mirabilis O13 lipopolysaccharide, which contains a unique component: an amide of D-galacturonic acid (D-GalA) with an unusual amino acid, Nepsilon-[(R)-1-carboxyethyl]-L-lysine (alaninolysine, AlaLys). Selective chemical degradations of either GalA or AlaLys resulted in the los...
