Schematic diagram showing the predicted features of LatA, including the signal sequence (amino acids 1 to 31), the passenger domain (amino acids 32 to 546), the ArgE/DapE/ACY1/CPG2/YscS-like metallopeptidase motif (amino acids 227 to 236; IPR001261), the α-helical linker domain (amino acids 556 to 583), and the β-barrel domain (amino acids 587 to 851). A putative structural model of the LatA β-barrel domain was generated using the Phyre program.
