Kcv_ATCV-1 sequence alignment with the sequence of the prototype chlorovirus K⁺ channel Kcv_PBCV-1 by ClustalW. The slide helix, outer transmembrane (TMD1) turret, pore helix, selectivity filter, and inner transmembrane (TMD2) of the Kcv_PBCV-1 are highlighted by the horizontal lines. Asterisks indicate positions which have a fully conserved residue. A colon indicates conservation between amino acids with strongly similar properties. A period indicates conservation between amino acids with less similar properties.
