Algal Neurotoxin Biosynthesis Repurposes the Terpene Cyclase Structural Fold Into an N-prenyltransferase

J. R. Chekan, S. M. K. McKinnie, J. P. Noel, B. S. Moore

The paper reports the structure and function of prenyltransferases from marine algae that repurpose the terpene cyclase fold for N-prenylation of glutamic acid, enabling the biosynthesis of neurotoxins like domoic acid.
