Example of a stable salt bridge interaction of the AA carboxylic acid headgroup with the sidechain of R65hASIC3, as well as interactions with Y58hASIC3. The ASIC protein is shown as cyan cartoon with interacting residues shown as cyan sticks. AA is shown as orange sticks. Interactions for a 200 ns section of a simulation with a total length of 500 ns are shown. The movie illustrates approximately 0.1 ns/frame, played at a speed of ∼200 ns/min.
