Protein Structure from Scientific Research

A structural model of EC18(rGMP)-RNaseHII(E17A) shown in a cylinders/stubs representation with individual components denoted. Lower: left, major protein-protein interactions of RNaseHII with the EC18(rGMP); middle and right, the substrate recognition and cleavage by transcription-coupled RNaseHII. Individual components are denoted, and the rG at position +16 is colored magenta with heteroatom-coloring. See alsoFigures S1andS2,Table S2, andVideo S3.
