Influenza proton pump, molecular model
Influenza proton pump. Molecular model showing the protein structure of a proton pump from an influenza virus. Proton pumps are membrane proteins that move protons across a cell membrane. This is tetrameric proton channel M2 in complex with the inhibitor drug rimantadine. In the closed state, four tightly packed transmembrane helices define a narrow channel. Rimantadine binds on the lipid-facing side of the channel, stabilizing the closed conformation. It is thought that drug-resistant mutations may counter this effect. This proton pump is from an H3N2 influenza A virus

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate molecular structure of an influenza proton pump. The image reveals the protein structure of a proton pump found in an influenza virus, specifically the tetrameric proton channel M2. Proton pumps are vital membrane proteins responsible for transporting protons across cell membranes. The black background enhances the visual impact, allowing us to focus on the detailed illustration and appreciate its scientific significance. In this closed state, four tightly packed transmembrane helices form a narrow channel that facilitates proton movement. Additionally, we can observe how rimantadine, an inhibitor drug used to treat influenza infections, binds to the lipid-facing side of the channel. This binding stabilizes the closed conformation and prevents viral replication. However, it is worth noting that drug-resistant mutations may arise and counteract rimantadine's effectiveness. Understanding these mutations is crucial for developing effective antiviral treatments against H3N2 influenza A viruses. This artwork beautifully combines biology and graphic design to provide a visually striking representation of this complex molecular system. It highlights various aspects related to biochemistry, cellular biology, microbiology, and proteomics.
