(a) Multiple sequence alignment of flavodoxins from Campylobacter jejuni (strain ATCC 700819), Hp (strain J99), Vibrio cholerae (strain ATCC 39541), Escherichia coli (strain K12), Salmonella enterica subsp. enterica serovar Typhi (strain Ty2) and Salmonella enterica subsp. enterica serovar Typhimurium (strain ATCC 700720). It has been performed with Clustal Omega [194]. (b) Sequence identity between Hp (strain J99) flavodoxin and that from Campylobacter jejuni (strain ATCC 700819), Vibrio cholerae (strain ATCC 39541), Escherichia coli (strain K12), Salmonella enterica subsp. enterica serovar Typhi (strain Ty2), and Salmonellaenterica subsp. enterica serovar Typhimurium (strain ATCC 700720). It has been calculated with Clustal Omega [194].
