| + | Pyruvate formate-lyase activating enzyme generates a stable and catalytically essential glycyl radical on G(734) of pyruvate formate-lyase via the direct, stereospecific abstraction of a hydrogen atom from pyruvate formate-lyase. The activase performs this remarkable feat by using an iron-sulfur cluster and S-adenosylmethionine (AdoMet), thus placing it among the AdoMet radical superfamily of enzymes. We report here structures of the substrate-free and substrate-bound forms of pyruvate formate-lyase-activating enzyme, the first structures of an AdoMet radical activase. To obtain the substrate-bound structure, we have used a peptide substrate, the 7-mer RVSGYAV, which contains the sequence surrounding G(734). Our structures provide fundamental insights into the interactions between the activase and the G(734) loop of pyruvate formate-lyase and provide a structural basis for direct and stereospecific H atom abstraction from the buried G(734) of pyruvate formate-lyase. | ||
