Structural comparison of AoRib2–DARIPP and BsRibG–AROPP. (a) Overall structure comparison of the deaminase domains of AoRib2 (cyan) and BsRibG (salmon). (b) Superposition of the structures of AoRib2–DARIPP and BsRibG–AROPP showing the evolutionary conservation of nucleobase-recognition residues. (c) Superposition of the structures of AoRib2–DARIPP and BsRibG–AROPP showing the structural divergence of phosphate- and ribose-recognition residues.
