The phylogenetic tree (A) and amino acid sequence alignment (B) of V. anguillarum Plp with members of the SGNH family. The phylogenetic tree was analyzed by the Neighbor Joining (NJ) method with 1000 bootstraps, and node support values (as percentages) are labeled above the branch lines of the phylogenetic tree leading to the Plp homologues found in the genus Vibrio. Sequences of the 16 closest matches to Plp are aligned along the five conserved blocks of the SGNH family (Block IV not shown). The rectangle bars above the alignment indicate the amount of conservation of amino acid residues. The four residues conserved in all SGNH family members are boxed.
