title: In vitro system for the synthesis of teichoic acid linked to peptidoglycan.
abstract: A crude cell wall preparation from Staphylococcus aureus H prepared by the method of Mirelman and Sharon (1972) was shown to catalyze the synthesis of polyribitol phosphate linked to the cell wall peptidoglycan. The reaction used cytidine diphosphate (CDP)-ribitol as a substrate and in addition required the presence of CDP-glycerol, uridine diphosphate (UDP)-N-acetyl-D-glucosamine, and adenosine triphosphate. Incubation of radioactive CDP-glycerol with the crude cell wall preparation resulted in the transfer of glycerol phosphate residues to the cell wall; this reaction was greatly stimulated by the presence of UDP-N-acetylglucosamine. These data suggest that polyribitol phosphate is linked to the cell wall peptidoglycan by an oligomer contaning N-acetyl-D-glucosamine and glycerol phosphate.
