Alignment of the amino acid sequences of Lin0142 and its homologs and orthologs in L. innocua and L. monocytogenes. The Crp-Fnr family protein from S. epidermidis ATCC 12228 (NP 765769) (labeled Crp-Fnr) also was included in the alignment. Black shading, amino acids that are identical in at least 50% of the sequences; grey shading, amino acids that are similar in at least 50% of the sequences. The putative winged-helix DNA-binding region is underlined.
