No activity toward ATP, phosphodiesters, glycerol-1-phosphate, glucose 1-phosphate, glucose 6-phosphate, NADP, GTP or 3',5'-cAMP, ADP or ATP. Also has a phosphotransferase activity catalyzing the transfer of low-energy phosphate groups from organic phosphate monoesters to free hydroxyl groups of various organic compounds. Capable of transferring phosphate from either pNPP or UMP to adenosine or uridine. Does not exhibit nucleotide phosphomutase activity.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB.
