FIG. 1.

N-terminal domain of LytE. Repeats and their sequence homology to the following cell wall-associated proteins are shown: muramidase-2 of Enterococcus hirae (6), muramidase of Enterococcus faecium (2), invasion-associated protein P60 of Listeria ivanovii and Listeria monocytogenes (4), muramidase of Lactococcus lactis (5), B. subtilis phage φ29 lysozyme (25), and amidases of the B. subtilis defective phage PBSX (7, 15). The consensus sequence is presented at the bottom of the figure (uppercase letters represent amino acids conserved in all examined proteins; lowercase letters represent conserved amino acids belonging to the same family).
