Here we report the discovery and functional analysis of two methyl transferases (MTs) that play crucial roles for ETP toxicity. Genome comparisons, knockouts, and in vitro enzyme studies identified a new S-adenosyl-l-methionine-dependent S-MT (TmtA) that is, surprisingly, encoded outside the gli gene cluster. We found that TmtA irreversibly inactivates ETP by S-alkylation and that this detoxification strategy appears to be not only limited to ETP producers. Furthermore, we unveiled that GliN functions as a freestanding amide N-MT. GliN-mediated amide methylation confers stability to ETP, damping the spontaneous formation of tri- and tetrasulfides. In addition, enzymatic N-alkylation constitutes the last step in gliotoxin biosynthesis and is a prerequisite for the cytotoxicity of the molecule. Thus, these specialized alkylating enzymes have dramatic and fully opposed effects: complete activation or inactivation of the toxin."xsd:string |
