Presqualene diphosphate synthase

Presqualene diphosphate synthase (EC 2.5.1.103, SSL-1 (gene)) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate:(2E,6E)-farnesyl-diphosphate farnesyltransferase (presqualene diphosphate forming).^[1] This enzyme catalyses the following chemical reaction

2 (2E,6E)-farnesyl diphosphate ${\displaystyle \rightleftharpoons }$ presqualene diphosphate + diphosphate

This enzyme is isolated from the green alga Botryococcus braunii BOT22.
