Accepted name: phosphomevalonate decarboxylase

Reaction: ATP + (R)-5-phosphomevalonate = ADP + phosphate + isopentenyl phosphate + CO2

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

Comments: The enzyme participates in a mevalonate pathway that occurs in archaea other than the extreme acidophiles of the Thermoplasmatales order. cf. EC, bisphosphomevalonate decarboxylase
