Structural Biology and Chemistry of the Terpenoid Cyclases.

The article provides insights in structural biology and chemistry of the terpenoid cyclases. Terpenoid cyclases catalyze the most complex chemical reactions occuring in the environment. They generate a unique hydrocarbon product with remarkable structural and stereochemical precision. The article also discusses monototerpene cyclases, diterpene cyclases, triterpene cyclases and antibody catalysis of cationic cyclization reactions.
