The enzyme pentalenene synthase (EC 4.2.3.7) catalyzes the chemical reaction

(2E,6E)-farnesyl diphosphate

\rightleftharpoons

pentalenene + diphosphate

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, pentalenene-forming). This enzyme is also called pentalenene synthetase.
