Reaction: ADP + ATP = phosphate + P1,P4-bis(5'-adenosyl) tetraphosphate
Other name(s): bis(5'-nucleosyl)-tetraphosphate phosphorylase (NDP-forming); diadenosinetetraphosphate αβ-phosphorylase; adenine triphosphate adenylyltransferase; diadenosine 5',5'"-P1,P4-tetraphosphate αβ-phosphorylase (ADP-forming); dinucleoside oligophosphate αβ-phosphorylase
Systematic name: ADP:ATP adenylyltransferase
Comments: GTP and adenosine tetraphosphate can also act as adenylyl acceptors.
