DE   AMP phosphorylase.
AN   AMPpase.
AN   nucleoside monophosphate phosphorylase.
CA   (1) AMP + phosphate = adenine + alpha-D-ribose 1,5-bisphosphate.
CA   (2) CMP + phosphate = alpha-D-ribose 1,5-bisphosphate + cytosine.
CA   (3) phosphate + UMP = alpha-D-ribose 1,5-bisphosphate + uracil.
CC   -!- The enzyme from archaea is involved in AMP metabolism and CO2
CC       fixation through type III RubisCO enzymes.
CC   -!- The activity with CMP and UMP requires activation by cAMP.
