Enzyme Commission Primary Name: geranyl diphosphate diphosphatase

Enzyme Commission Synonyms: geraniol synthase, geranyl pyrophosphate pyrophosphatase, GES, CtGES

Standard Gibbs Free Energy (ΔrG in kcal/mol): -3.742981Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Isolated from Ocimum basilicum (basil) and Cinnamomum tenuipile (camphor tree). Requires Mg2+ or Mn2+. The mechanism involves a geranyl cation [Iijima04]. Neryl diphosphate is hydrolysed more slowly. May be the same as EC monoterpenyl-diphosphatase.
