Multiple alignment of bacterial genome sequences and a part of HSR1. A part of HSR1 sequence from 240 to 604 was aligned with four representative bacterial genomes. The start codons for the chloride channel protein ORFs are indicated by three consecutive asterisks. An additional nucleotide (arrowhead) in the HSR1 ORF, which would be present due to an insertion or perhaps a sequencing error, was removed to deduce the protein sequence. Residues identical in four or five sequences are highlighted on black background. GenBank accession numbers and positions for the nucleotide sequences are: Burkholderia, NZ_ABBH01000052.1:1764-2131; Lutiella, NZ_ACIS01000003.1:194423-194791; Ralstonia, NZ_AAKL01000043.1:37423-37060; Delftia, NC_010002.1: 1926518-1926158.
