The C-P lyase complex in bacteria catalyzes the transformation of phosphonates to orthophosphate under conditions of phosphate starvation. The first committed step in the C-P lyase-catalyzed reaction is the displacement of adenine from MgATP by phosphonate substrates, yielding ribose-1-phosphonate-5-triphosphate. In
