Halomethane biosynthesis: structure of a SAM-dependent halide methyltransferase from Arabidopsis thaliana

Angew Chem Int Ed Engl. 2010 May 10;49(21):3646-8. doi: 10.1002/anie.201000119.

Abstract

A product structure of the halomethane producing enzyme in plants (Arabidopsis thaliana) is reported and a model for presentation of chloride/bromide ion to the methyl group of S-adenosyl-L-methionine (SAM) is presented to rationalise nucleophilic halide attack for halomethane production, gaseous natural products that are produced globally.
