Summary Phosphoroguanidates, a class of compounds which includes the enzymatically-active phosphagens, exhibit exceptionalin vitro stability. This lack of reactivity implies anin vivo mode of activation, as yet undiscerned. A variety of metal ions catalyse the cleavage of the phosphorus-nitrogen bond with consequent phosphoryl-group transfer, but the enhancement of rate seems insufficient to account for the known activities of phosphoro-creatine and phosphoro-arginine. It is suggested that yet another mode of activation, chemical or biochemical, awaits discovery.
