The Crystal Structure of the Human AAA+ Protein RuvBL1

 

The crystal structure of the molecular machine RuvBL1/RuvBL2 complex reveals a dodecamer consisting of two heterohexameric rings with alternating RuvBLl and RuvBL2 monomers bound to ADP/ATP. Our structural, biochemical and SAXS results give relevant insights into the assembly and illuminate the mechanism of how these proteins might exert their activities.
