Abstract

Analysis of the hydrocarbons produced during catalysis by mutants of aristolochene synthase from Penicillium roqueforti indicated that Trp 334 had a pivotal function for the efficient production of aristolochene from farnesylpyrophosphate most likely by stabilising the intermediate, eudesmane cation.
