This domain is the catalytic domain of ATP-sulfurylase or sulfate adenylyltransferase EC:2.7.7.4 some of which are part of a bifunctional polypeptide chain associated with adenosyl phosphosulphate (APS) kinase Pfam:PF01583. Both enzymes are required for PAPS (phosphoadenosine-phosphosulfate) synthesis from inorganic sulphate [2]. ATP sulfurylase catalyses the synthesis of adenosine-phosphosulfate APS from ATP and inorganic sulphate [1].	Domain
A, B, C	PF01583	Adenylylsulphate kinase (APS_kinase)	Adenylylsulphate kinase	Enzyme that catalyses the phosphorylation of adenylylsulphate to 3'-phosphoadenylylsulfate. This domain contains an ATP binding P-loop motif.	Domain
