FlgJ cell-wall hydrolyzing activity enhances, but is not required, for flagellum assembly in Salmonella enterica

Salmonella can assemble functional flagella, even when the acetylglucosaminidase activity of FlgJ is genetically inactivated, showing that early steps in flagellar assembly are more diverse than previously thought and that differences in cell wall structure between gram-positive and -negative bacteria likely determine whether a cell wall hydrolyzing activity is required for flagellum assembly.
