PubMed Abstract:
Linalool dehydratase/isomerase (Ldi), an enzyme of terpene degradation in Castellaniella defragrans, isomerizes the primary monoterpene alcohol geraniol into the tertiary alcohol (S)-linalool and dehydrates (S)-linalool to the alkene β-myrcene. Here we report on the crystal structures of Ldi with and without terpene substrates, revealing a cofactor-free homopentameric enzyme. The substrates were embedded inside a hydrophobic channel between two monomers of the (α,α)6 barrel fold class and flanked by three clusters of polar residues involved in acid-base catalysis. The detailed view into the active site will guide future biotechnological applications of Ldi, in particular, for industrial butadiene and isoprene production from renewable sources.
