The NS2B/NS3 two-component protease from West Nile virus. The NS3 protein is visualised as an electrostatic surface with red regions being acidic, and blue regions being basic. White regions are neutral or hydrophobic in nature. A short segment of the NS2B "cofactor" protein is shown as coloured sticks. The isoleucine 60 residue (magenta), and tryptophan 62 (yellow) residues are critical for NS2B binding to NS3.

Today we celebrate the life of Warren DeLano. Warren is best known for his development of PyMOL, the tool we use almost every day to depict 3D molecular structure of small molecules and proteins.
