Pyrrolopyrimidine containing natural products are widely distributed in Nature. The biosynthesis of the 7-deazapurine moiety that is common to all pyrrolopyrimidines entails multiple steps, one of which is a complex radical-mediated ring contraction reaction catalyzed by CDG synthase. Herein we review the biosynthetic pathways of deazapurines, focusing on the biochemical and structural insights into CDG synthase.
