Glossary: C30 botryococcene = (10S,13R)-10-ethenyl-2,6,10,13,17,21-hexamethyldocosa-2,5,11,16,20-pentaene

Other name(s): SSL-3 (gene name)

Systematic name: C30 botryococcene:NADP+ oxidoreductase

Comments: Isolated from the green alga Botryococcus braunii BOT22. Acts in the reverse direction. Involved in the production of botryococcenes, which are triterpenoid hydrocarbons of isoprenoid origin produced in large amount by this alga.
