Copal-8-ol diphosphate hydratase

Copal-8-ol diphosphate hydratase (EC 4.2.1.133, CcCLS) is an enzyme with systematic name geranylgeranyl-diphosphate hydro-lyase ((13E)-8alpha-hydroxylabda-13-en-15-yl diphosphate forming).^[1] This enzyme catalyses the following chemical reaction

(13E)-8alpha-hydroxylabda-13-en-15-yl diphosphate

\rightleftharpoons

geranylgeranyl diphosphate + H₂O

This enzyme requires Mg²⁺.
