Here, we report a carbon-carbon cross-link between two unfunctionalized side chains. This valine-phenyalanine cross-link, produced in an oxygen-dependent reaction, is generated by its own carboxylate-bridged diiron center and serves to stabilize the metallocenter. This finding opens the door to new types of posttranslational modifications, and it demonstrates new catalytic potential of diiron centers. A diiron protein autogenerates a valine-phenylalanine cross-link.,Cooley RB, Rhoads TW, Arp DJ, Karplus PA Science. 2011 May 20;332(6032):929.
