A promiscuous ancestral enzyme´s structure unveils protein variable regions of the highly diverse metallo-β-lactamase family
Abstract
The structure of Igni18, ancient enzyme from the Crenarchaean species Ignicoccus hospitalis, is solved and characterized by Pérez-García, Chow and colleagues. This structure provides insight as to the evolution of metallo-beta-lactamases and their functions.
