3D structure of DENV NS2B-NS3 protease: (a) ribbon diagram of the two protein chains; Chain A (Green color) shows the NS2B cofactor and Chain B (Red color) represents the NS3pro domain, and (b) graphical representation of the DENV protease NS3pro domain labelled with the total number of amino acid residues, atoms, heavy atoms and net charge, and predicted secondary structure elements (tube = alpha helix, arrows = beta sheets).
