Neoabietadiene synthase - Misplaced Pages

Neoabietadiene synthase (EC 4.2.3.132, AgAS, PtTPS-LAS) is an enzyme with systematic name (+)-copaly-diphosphate diphosphate-lyase (cyclizing, neoabietadiene-forming). This enzyme catalyses the following chemical reaction:

(+)-copalyl diphosphate

\rightleftharpoons

neoabietadiene + diphosphate

This enzyme is isolated from Abies grandis (grand fir).
