The Mechanisms of Radical SAM/Cobalamin Methylations: An Evolving Working Hypothesis.

Author(s): K. K. J. Chan, S. Thompson, D. O'Hagan

All about Me: Pierre and co-workers have revealed mechanistic details of a tryptophan methyltransferase (TsrM) involved in the biosynthesis of the thiopeptide antibiotic, thiostrepton. Utilising cobalamin and a [4Fe–4S] cluster to generate 2-methyltryptophan from tryptophan, a key difference between this enzyme and other radical SAM methyltransferases is that the reaction is not initiated by a single-electron reduction of SAM to generate 5′-dA⋅.
