Alignments of the cytolysin-encoding genes of the 3 E. faecalis strains and amino acid alignments of the three cytolysin types. (a) The cytolysin gene cluster (cytL-L1 and cytL-S1, cyt-LS-fusion) and its neighboring region were extracted from 3 strains (JARB-HU0762, HU0680, HU0828) and compared. The grayscale indicates the percent sequence identity. (b) Amino acid alignment of three types of cytolysin, namely, CytL-La + CytL-Sa, CytL-Lb + CytL-Sb and cytolysin-LS-fusion.
