IntEnz Enzyme Nomenclature


Accepted name:
phosphomevalonate decarboxylase
Systematic name:
ATP:(R)-5-phosphomevalonate carboxy-lyase (adding ATP; isopentenyl-phosphate-forming)



The enzyme participates in a mevalonate pathway that occurs in halophilic archaea. The activity is also present in eubacteria of the Chloroflexi phylum. cf. EC, diphosphomevalonate decarboxylase, and EC, bisphosphomevalonate decarboxylase. The enzyme participates in a mevalonate pathway that occurs in archaea other than the extreme acidophiles of the Thermoplasmatales order. cf. EC, bisphosphomevalonate decarboxylase.
