FIG. 2.

Sortase substrates. A schematic representation of L. monocytogenes LPXTG and NXXTX proteins is shown. The numbers within domains indicate the number of repeats. Nineteen proteins are absent in L. innocua and are indicated in green letters. Proteins detected in the L. monocytogenes cell wall fraction (146) are indicated by an arrow. The two sortase B substrates, Lmo2185 and Lmo2186, are drawn on the right of LPXTG proteins. AA, amino acids. (Adapted from reference 30 with permission from Elsevier.)
