Sysname
AMP:phosphate alpha-D-ribosyl 5'-phosphate-transferase
Reaction(IUBMB)
(1) AMP + phosphate = adenine + alpha-D-ribose 1,5-bisphosphate [RN:
R10836 ];
(2) CMP + phosphate = cytosine + alpha-D-ribose 1,5-bisphosphate [RN:
R10837 ];
(3) UMP + phosphate = uracil + alpha-D-ribose 1,5-bisphosphate [RN:
R10838 ]
Reaction(KEGG)

Comment
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].
