Figure 4.
Fig. 4. Conservation of binding-site residues amongst flavivirus family members. Black background denotes nonsimilar substitutions, and the shaded rectangles bring attention to residues where increased variability is observed. Numbering for YF is noted and is used throughout the manuscript to describe all MTase residues. Residues with side chains within hydrogen-bonding distance of GTP are marked with an asterisk (*). Residues with backbone carbonyl groups interacting with the conserved water and the guanine ring are marked with the symbol (@).
