About 11-cis Retinal
As noticed with other Kv channels, EM density is noticeable in the middle of the selectivity filter (Fig. 1B; Determine S4C, Supplementary Materials) similar to the common density of unique K+ ions. A complete of 4 websites of potassium ions might be modeled coordinating the residues forming the selectivity filter. Right before entering the Kv hou
