EC 2.7.1.25

Accepted name: adenylyl-sulfate kinase

Reaction: ATP + adenylyl sulfate = ADP + 3'-phosphoadenylyl sulfate

Glossary: 3'-phosphoadenylyl sulfate = PAPS

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

Comments: 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 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).

EC 2.7.1.26

Accepted name: riboflavin kinase

Reaction: ATP + riboflavin = ADP + FMN

For diagram of reaction click here.

Other name(s): flavokinase; FK; RFK

Systematic name: ATP:riboflavin 5'-phosphotransferase

Comments: The cofactors FMN and FAD participate in numerous processes in all organisms, including mitochondrial electron transport, photosynthesis, fatty-acid oxidation, and metabolism of vitamin B6, vitamin B12 and folates [5]. While monofunctional riboflavin kinase is found in eukaryotes, some bacteria have a bifunctional enzyme that exhibits both this activity and that of EC 2.7.7.2, FMN adenylyltransferase [5]. A divalent metal cation is required for activity (with different species preferring Mg2+, Mn2+ or Zn2+). In Bacillus subtilis, ATP can be replaced by other phosphate donors but with decreasing enzyme activity in the order ATP > dATP > CTP > UTP [6].
