The Periodic Table of the Elements, developed independently by Mendeleev and Meyer in 1869, represents a remarkable achievement leading to improved understanding of the electronic structure of the atoms and the chemical and physical properties of the elements. In recognition of this milestone, the Unit...
Structure of the active site in the ADP·Pi state The cryo-EM density in D1 revealed an ADP molecule surrounded by multiple unexplained patches of density, extending from the β-P (Fig. 2a and Extended Data Fig. 1a) and close to the arginine finger R359. To ascertain the chemical identi...
