Extended Data Fig. 5: VSDs of CNGC5 and CNGC1 in comparative perspective with other CNBD Channels.

From: Cryo-EM structures of Arabidopsis CNGC1 and CNGC5 reveal molecular mechanisms underlying gating and calcium selectivity

Extended Data Fig. 5

a, Sequence alignment of S4 helix among 20 Arabidopsis CNGCs. Red asterisks indicate the conserved arginine site. b, VSDs of CNGC5, CNGC1, HCN1(PDB:5U6P) and KAT1(PDB:6V1X) are shown in side view, with the S1 helix omitted for clarity. The positive charged (or polar) residues on S4 and the gating charge transfer center residues on S2 and S3 are shown as sticks.
