Publication Abstract from PubMed
RNase HII exists ubiquitously in organisms and functions as a monomer in prokaryotes. We determined the crystal structure of Staphylococcus aureus RNase HII (Sa-RNase HII), which displays a novel dimer conformation, with the active site of each monomer covered by the other one. Both small-angle X-ray scattering and gel-filtration analysis confirmed that Sa-RNase HII exists as a homodimer in solution. Enzymatic analysis revealed that the "self-inhibited" dimeric form is catalytically active. Furthermore, continuous-wave electron paramagnetic resonance experiments clarified that the Sa-RNase HII dimer undergoes a large conformational change upon substrate binding, but remains a dimer to catalyze the reaction. Our structural and biochemical studies identified a novel functional dimer of Sa-RNase HII with distinct regulation mechanism for its catalytic activity.
