UniProt functional annotation for Q97UL5

UniProt code: Q97UL5.

Organism: Saccharolobus solfataricus (strain ATCC 35092 / DSM 1617 / JCM 11322 / P2) (Sulfolobus solfataricus).
Taxonomy: Archaea; Crenarchaeota; Thermoprotei; Sulfolobales; Sulfolobaceae; Saccharolobus.
 
Function: Catalyzes the decarboxylation of mevalonate 5-diphosphate (MVAPP) to isopentenyl diphosphate (IPP). Functions in the mevalonate (MVA) pathway leading to IPP, a key precursor for the biosynthesis of isoprenoid compounds such as archaeal membrane lipids. {ECO:0000269|PubMed:23378249}.
 
Catalytic activity: Reaction=(R)-5-diphosphomevalonate + ATP = ADP + CO2 + isopentenyl diphosphate + phosphate; Xref=Rhea:RHEA:23732, ChEBI:CHEBI:16526, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:57557, ChEBI:CHEBI:128769, ChEBI:CHEBI:456216; EC=4.1.1.33; Evidence={ECO:0000269|PubMed:23378249};
Pathway: Isoprenoid biosynthesis; isopentenyl diphosphate biosynthesis via mevalonate pathway; isopentenyl diphosphate from (R)-mevalonate: step 3/3. {ECO:0000269|PubMed:23378249}.
Subunit: Homodimer. {ECO:0000250}.
Similarity: Belongs to the diphosphomevalonate decarboxylase family. {ECO:0000305}.
