Insights into the stereochemical mechanism of the B 12 -dependent radical SAM glutamine C- methyltransferase (QCMT)
Abstract Methyl-coenzyme M reductase (MCR) is a crucial enzyme for methanogenesis and harbors several unusual post-translational modifications. Recent studies have identified glutamine C-methyltransferase (QCMT), as a B12-dependent radical SAM enzyme responsible for methylating a glutamine residue within the MCR active site. B12-dependent radical SAM enzymes have the remarkable ability to alkylate unactivated Csp2- and Csp3-atoms in a stereoselective manner.
Structural and mechanistic basis for RiPP epimerization by a radical SAM enzyme - Nature Chemical Biology
Abstract d-Amino acid residues, found in countless peptides and natural products including ribosomally synthesized and post-translationally modified peptides (RiPPs), are critical for the bioactivity of several antibiotics and toxins.
