Figure 2From: The solution structure of the prototype foamy virus RNase H domain indicates an important role of the basic loop in substrate bindingSolution structure of PFV RNase H. (A) Superposition of the 19 lowest energy structures. (B) Ribbon diagram of the lowest energy structure. The C-helix is highlighted in magenta, and the basic loop in orange. The active site residues D599, E646, D669 and D740 are highlighted in bright green.Back to article page
