Predicted to enable adenylylsulfate kinase activity; protein homodimerization activity; and sulfate adenylyltransferase (ATP) activity. Predicted to be involved in 3'-phosphoadenosine 5'-phosphosulfate biosynthetic process and sulfate assimilation. Orthologous to human PAPSS1 (3'-phosphoadenosine 5'-phosphosulfate synthase 1).
