The bacterial C-Plyase pathway is responsible for the metabolism of unactivated organophosphonates under conditions of phosphate starvation. The cleavage of the C-P bond within ribose-1-methylphosphonate-5-phosphate to form methane and 5-phospho-ribose-1,2-cyclic phosphate (PRcP) is catalyzed by the radical SAM enzyme PhnJ. In Escherichiacoli the cyclic phosphate product is hydrolyzed to ribose-1
