Nowotny_Dec2010_fig1 - enlarged view

Figure 1.  The overall structure of T. maritima RNase H2 in complex with nucleic acid substrate – a 12-mer double-stranded DNA with single ribonucleotide. The protein is shown in green (the catalytic domain) and cyan (C-terminal helical domain). The nucleic acid is shown in purple with the single ribonucleotide in red. The carboxylate residues forming the active site are shown in orange ball-and-stick and the tyrosine residue at the heart of the RNA-DNA junction recognition module in yellow. Two magnesium ion bound at the active site are shown as purple spheres.
