FNT channels with unique constriction sites. FNT channels with less hydrophobic cytoplasmic slit in the (a) closed (UniProt ID: L8XVV6 from YfdC-α; CHI value: +3.7) and (b) open (UniProt ID: D5BVC1 from NirC-α; CHI value: +3.1) states. (c) FNT channel with less hydrophobic central constriction site (UniProt ID: Q1Q4Z9- unclassified; CHI value: -2.8). (d) FNT channel with a wider cytoplasmic slit in the closed state (UniProt ID: M0BPP6 from YfdC-β; CVV value: 407 Ǻ3). (e) FNT channel with a narrower cytoplasmic slit in the open state (UniProt ID: I0JHL8 from an unclassified FNT channel; CVV value: 620 Ǻ3). (f) FNT channel with a narrower central constriction (UniProt ID: B9DL87 from NirC-γ; CVV value: 529 Ǻ3)
