ATOMIC STRUCTURE OF THE RUVC RESOLVASE: A HOLLIDAY JUNCTION-SPECIFIC ENDONUCLEASE FROM E. COLI
Overview
The crystal structure of the RuvC protein, a Holliday junction resolvase from E. coli, has been determined at 2.5 A resolution. The enzyme forms a dimer of 19 kDa subunits related by a dyad axis. Together with results from extensive mutational analyses, the refined structure reveals that the catalytic center, comprising four acidic residues, lies at the bottom of a cleft that nicely fits a DNA duplex. The structural features of the dimer, with a 30 A spacing between the two catalytic centers, provide a substantially defined image of the Holliday junction architecture. The folding topology in the vicinity of the catalytic site exhibits a striking similarity to that of RNAase H1 from E. coli.
