Organometallic and radical intermediates reveal mechanism of diphthamide biosynthesis

Diphthamide biosynthesis involves a carbon-carbon bond forming reaction catalyzed by a radical S-adenosylmethionine (SAM) enzyme that cleaves a C-S bond in SAM to generate a 3-amino-3-carboxypropyl (ACP) radical. Using rapid freezing, we have captured an organometallic intermediate with an Fe-C bond...
