Abstract Whole filaments of autotrophically grown Anabaena cylindrica and heterocysts isolated from them will assimilate and metabolise exogenous glucose. Radiorespirometric experiments suggest the operation of the pentose phosphate pathway. Glucose-6-phosphate and 6-phosphogluconate dehydrogenase are present in heterocysts at 6–8 times the levels found in vegetative cells whereas enzymes of the reductive pentose phosphate and glycolytic pathways are barely or not detectable. Glucose-6-phosphate dehydrogenase in vegetative cells, but not in heterocysts is subject to inhibition by ribulose diphosphate.
