Studies on the Physiology of Rickettsiae Iii

Paretsky, D. (University of Kansas, Lawrence), R. A. Consigli, and C. M. Downs. Studies on the physiology of rickettsiae. III. Glucose phosphorylation and hexokinase activity in Coxiella burnetii. J. Bacteriol. 83:538-543. 1962.-Disrupted Coxiella burnetii preparations phosphorylate glucose by a hexokinase system. Glucose-6-phosphate-P(32), synthesized by the rickettsiae in the presence of P(32)-labeled carbamyl phosphate and glucose, has been isolated as the barium salt and by ion exchange and paper chromatography. C. burnetii hexokinase activity is inhibited by high concentrations of adenosine mono-, di-, and triphosphates, suggesting similarities to hexokinase from other sources.
