Domain

Phosphoadenosine phosphosulphate reductase (IPR002500)

Short name: PAPS_reduct

Domain relationships

Description

This domain is found in phosphoadenosine phosphosulphate (PAPS) reductase enzymes or PAPS sulphotransferase. PAPS reductase is part of the adenine nucleotide alpha hydrolases superfamily also including N type ATP PPases and ATP sulphurylases [PMID: 9261082]. The enzyme uses thioredoxin as an electron donor for the reduction of PAPS to phospho-adenosine-phosphate (PAP) [PMID: 9261082, PMID: 7588765]. It is also found in NodP nodulation protein P from Rhizobium meliloti (Sinorhizobium meliloti) which has ATP sulphurylase activity (sulphate adenylate transferase) [PMID: 2250719].
