1.A.51.1.5
Proton channel protein, NpHv1 of 239 aas and 4 TMSs.  Proton selectivity, and pH- and voltage-dependent gating have been demoonstrated. Mutations in the first transmembrane segment at position 66 (Asp66), the presumed selectivity filter, led to a loss of proton-selective conduction (Chaves et al. 2016).
