Accepted name: AMP phosphorylase
Reaction: (1) AMP + phosphate = adenine + α-D-ribose 1,5-bisphosphate
(2) CMP + phosphate = cytosine + α-D-ribose 1,5-bisphosphate
(3) UMP + phosphate = uracil + α-D-ribose 1,5-bisphosphate

Other name(s): AMPpase; nucleoside monophosphate phosphorylase; deoA (gene name)
Systematic name: AMP:phosphate α-D-ribosyl 5′-phosphate-transferase
Comments: The enzyme from archaea is involved in AMP metabolism and CO2 fixation through type III RubisCO enzymes. The activity with CMP and UMP requires activation by cAMP [2].
