Abstract

Summary: Cell extracts of and were examined for enzymes of intermediary carbohydrate metabolism using a sensitive radiochemical assay procedure. For , the enzyme activities detected were supporting evidence for the existence of a glycolytic pathway giving lactate anaerobically and acetate aerobically. also had activities of many glycolytic enzymes. Enzymes of the pentose phosphate pathway occurred in both and Their presence allowed the proposal of a sequence for the synthesis from glycolytic pathway intermediates of ribose 5-phosphate, and hence phosphoribosyl diphosphate, for the synthesis of nucleotides. Pathways for the further metabolism of deoxyribose I-phosphate and ribose 1-phosphate produced from nucleoside phosphorylase reactions operated in extracts from both organisms.
