Sulphate adenylyltransferase, prokaryotic-type (IPR020792)

Short name: SO4_adenylyltransferase_pro

Overlapping homologous superfamilies

Family relationships



ATP-sulfurylase catalyses a key reaction in the global sulfur cycle by reversibly converting inorganic sulfate with ATP to adenosine 5'-phosphosulfate (APS) and pyrophosphate (PPi) [PMID: 24073218]. This entry consists of sulphate adenylyltransferase or ATP-sulfurylase (EC:, mainly from prokaryotes. It also includes ATP-sulfurylase from the enteric protozoan parasite Entamoeba, which is closest to Synechocystis and Bacillus subtilis ATP-sulfurylases [PMID: 9920405]. In higher eukaryotes, APS kinase is N-terminally fused to ATP-sulfurylase.
