'''(-)-alpha-cuprenene synthase''' ({{EC number|4.2.3.95}}, ''Cop6'') is an [[enzyme]] with system name ''(-)-alpha-cuprenene hydrolase (cyclizing, (-)-alpha-cuprenene-forming)''.<ref>{{cite journal | title = Sesquiterpene synthases Cop4 and Cop6 from <em>Coprinus cinereus</em>: catalytic promiscuity and cyclization of farnesyl pyrophosphate geometric isomers |author = Lopez-Gallego, F., Agger, S.A., Abate-Pella, D., Distefano, M.D. and Schmidt-Dannert, C. |journal = Chembiochem. |year = 2010 |volume = 11 |pages = 1093–1106 |pmid = 20419721}}</ref> This enzyme [[catalysis|catalyses]] the following [[chemical reaction]]

: (2E,6E)-farnesyl diphosphate <math>\rightleftharpoons</math> (-)-alpha-cuprenene + [[diphosphate]]

The enzyme from the [[fungus]] ''[[Coprinopsis cinerea]]'' produces (-)-alpha-cuprenene with high selectivity.
