Fig. 2From: Genome-wide survey and phylogeny of S-Ribosylhomocysteinase (LuxS) enzyme in bacterial genomesLuxS protein sequences of bacterial species from each cluster, showing conserved structural motifs. Each colour corresponds to a conserved motif. Motifs having same colour in all the five sequences represents motifs common to sequences from all the five clusters, while motifs having non-equivalent colours represent motifs unique to the sequences of the clusterBack to article page
