Glossary: Δ6-protoilludene = (4aS,7aS,7bR)-3,6,6,7b-tetramethyl-2,4,4a,5,6,7,7a,7b-octahydro-1H-cyclobuta[1,2-e]indene

Other name(s): 6-protoilludene synthase

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, Δ6-protoilludene-forming)

Comments: Isolated from the fungus Armillaria gallica. Δ6-Protoilludene is the first step in the biosynthesis of the melleolides.
