Abstract
Aristolochene synthase is a sesquiterpene cyclase that catalyses the high-precision conversion of farnesyl diphosphate to the sesquiterpene (+)-aristolochene via a tightly chaperoned carbocationic reaction cascade. This article examines recent work focussed on understanding the role this and other related enzymes play in controlling this chemistry. Through the use of X-ray crystallography, site-directed mutagenesis and substrate analogues, a better picture of how such proteins manipulate carbocations to arrive at specific hydrocarbon products is emerging.
