Figure 2.

Alignment of the deduced amino acid sequences from the slpH genes from all of the different sequence types (STs). The solid lines represent aligned amino acid sequences. Gaps between the lines represent gaps in the alignment. The length of the amino acid sequence is given for all of the STs. The degree of amino acid conservation among the different sequences is shown with a gradient ranging from white to black. White regions indicate 100% conservation, whereas black regions indicate 0% conservation. The proteins were compared to each other in silico using InterProScan. The red horizontal bars indicate the tandem SLAP domain (InterPro accession number IPR024968). The blue and green bars represent conserved motifs (PRINTS) of the Lactobacillus surface layer protein family (InterPro accession number PR01729) and the signal peptide domains, respectively.
