EC 2.7.1.25 Details
EC number
2.7.1.25
Accepted name
adenylyl-sulfate kinase
Reaction
ATP + adenylyl sulfate = ADP + 3′-phosphoadenylyl sulfate
Other name(s)
adenylylsulfate kinase (phosphorylating), 5′-phosphoadenosine sulfate kinase, adenosine 5′-phosphosulfate kinase, adenosine phosphosulfate kinase, adenosine phosphosulfokinase, adenosine-5′-phosphosulfate-3′-phosphokinase, APS kinase
Systematic name
ATP:adenylyl-sulfate 3′-phosphotransferase
CAS registry number
9012-38-8
Comment
The human phosphoadenosine-phosphosulfate synthase (PAPSS) system is a bifunctional enzyme (fusion product of two catalytic activities). In a first step, sulfate adenylyltransferase catalyses the formation of adenosine 5′-phosphosulfate (APS) from ATP and inorganic sulfate. The second step is catalysed by the adenylylsulfate kinase portion of 3′-phosphoadenosine 5′-phosphosulfate (PAPS) synthase, which involves the formation of PAPS from enzyme-bound APS and ATP. In contrast, in bacteria, yeast, fungi and plants, the formation of PAPS is carried out by two individual polypeptides, sulfate adenylyltransferase (EC 2.7.7.4) and adenylyl-sulfate kinase (EC 2.7.1.25).
