Chlorovirus encoded K⁺ channels. (a) Cartoon representations of a snapshot of Kcv_S taken from MD simulation at 80 ns of the production run. Left: Side view of the channel (two opposing monomer units). Right: view from bottom to top of the full tetrameric channel. Potassium ions are shown as red spheres, and F78 as explicit side chains in red. (b) Sequence alignment of three viral encoded K⁺ channels. The position of the transmembrane domains TMD1 and TMD2 as well as the pore helix are indicated by bars. The sequences are 86% identical; amino acid differences are highlighted in gray.
