WebHerein, we use TsrM as a model to describe methods that we have used to generate soluble protein that is purified in an active form with both cobalamin and [4Fe-4S] cluster cofactors bound. Additionally, we highlight the methods that we developed to characterize the enzyme following purification. WebHerein, we report structures of TsrM from Kitasatospora setae, which are the first structures of a cobalamin-dependent radical SAM methylase. Unexpectedly, the structures show an essential arginine residue that resides in the proximal coordination sphere of the cobalamin cofactor, and a [4Fe–4S] cluster that is ligated by a glutamyl residue ...

WebApr 21, 2024 · TsrM is a cobalamin-dependent radical S-adenosylmethionine (SAM) methyltransferase belonging to the Class B radical SAM methylase (RSM) family. This enzyme catalyzes the C-2 methylation of L-tryptophan to produce 2-methyltrytophan (2-MeTrp), an intermediate involved in the biosynthesis of thiostrepton A.
