Possesses dinucleoside triphosphate hydrolase activity (PubMed:18694747). Cleaves P(1)-P(3)-bis(5'-adenosyl) triphosphate (Ap3A) to yield AMP and ADP (PubMed:18694747). Exhibits adenylylsulfatase activity, hydrolyzing adenosine 5'-phosphosulfate to yield AMP and sulfate (PubMed:18694747). Exhibits adenosine 5'-monophosphoramidase activity, hydrolyzing purine nucleotide phosphoramidates with a single phosphate group such as adenosine 5'monophosphoramidate (AMP-NH2) to yield AMP and NH2 (PubMed:18694747). Exhibits adenylylsulfate-ammonia adenylyltransferase, catalyzing the ammonolysis of adenosine 5'-phosphosulfate resulting in the formation of adenosine 5'-phosphoramidate (PubMed:26181368). H2O + P(1),P(3)-bis(5'-adenosyl) triphosphate = ADP + AMP + 2 H(+) adenosine 5'-phosphosulfate + H2O = AMP + 2 H(+) + sulfate adenosine 5'-phosphosulfate + NH4(+) = adenosine 5'-phosphoramidate + 2 H(+) + sulfate adenosine 5'-phosphoramidate + H2O = AMP + NH4(+)
