Barley seed (Hordeum vulgare L.) homogenates contain an apparent enzymatic activity which catalyzes the synthesis of adenosine 5'-phosphorofluoridate from magnesium-adenosine 5'-triphosphate and sodium fluoride. Formation of this compound may interfere with some adenyl cyclase assays which use fluoride as a component of the incubation medium. Neither adenyl cyclase activity nor endogenous adenosine 3': 5'-monophosphate was detected in barley seed homogenates or extracts.
