Adenosine 3'-phosphate 5'-phosphosulfate is a high energy sulfate donor[1].

ChEBI: 3'-phospho-5'-adenylyl sulfate is an adenosine bisphosphate having monophosphate groups at the 3'- and 5'-positions and a sulfo group attached to the phosphate at position 5'. It has a role as an Escherichia coli metabolite and a mouse metabolite. It is an adenosine bisphosphate, an acyl sulfate and a purine ribonucleoside bisphosphate. It is functionally related to a 5'-adenylyl sulfate and an adenosine 3',5'-bismonophosphate. It is a conjugate acid of a 3'-phosphonato-5'-adenylyl sulfate(4-).
