Chains	Enzyme Name	Description	Catalytic Residues
D	alpha-D-ribose 1-methylphosphonate 5-phosphate C-P-lyase M-CSA #949	This radical SAM (AdoMet) enzyme is part of the C-P lyase complex, which is responsible for processing phophonates into usable phosphate. The enzyme from the bacterium Escherichia coli can act on additional alpha-D-ribose phosphonate substrates with different substituents attached to the phosphonate phosphorus (e.g. alpha-D-ribose-1- (N-(phosphonomethyl)glycine)-5-phosphate and alpha-D-ribose-1-(2-N- acetamidomethylphosphonate)-5-phosphate).
