Protein Structure from Scientific Research

Major protein-protein interactions of RNaseHII with the EC18. Upper left: overview of the EC18-RNaseHII complex. The arrow indicates the moving direction of DNA during transciption elongation. Upper right and lower: magnified view of the boxed region. The RNAP beta' subunit is colored blue, and the RNaseHII is colored in cyan with the alpha helix shown in cylinders. Interacting residues are labeled and shown as sticks. Black dash lines denote H-bonds and salt bridges.
