Phosphoadenosine phosphosulphate/adenosine 5'-phosphosulphate reductase (IPR004511)

Short name: PAPS/APS_Rdtase

Overlapping homologous superfamilies

Family relationships


This entry represents a family of phosphoadenosine phosphosulphate (PAPS) reductases and adenosine 5'-phosphosulphate (APS) reductases involved in the assimilatory reduction of inorganic sulphate. The APS reductases can be distinguished from the PAPS reductases by the presence of two additional cysteine pairs thought to form an iron-sulphur cluster [PMID: 11940598].
