Abstract

The dinitrophenyl-derivative of N-glycylglucosamine was isolated from partially hydrolyzed dinitrophenylated cell walls of Halococcus morrhuae CCM 859. To increase the yield of amino-terminal glycine residues, halococcal cell walls were treated with alkali or acid prior to dinitrophenylation. Authentic N-glycyl-glucosamine was used as a reference substance. A substitution of the amino group of glucosamine by an amino acid has so far not been found in any other wall of a pro- or eucaryotic cell. Since only 5% of the glycine residues reveal an unsubstituted carboxyl group within intact cell walls, glycine may play a role in connecting glycan strands through peptidic linkages between the amino group of glucosamine and the carboxyl group of an uronic acid or gulosaminuronic acid.
