Note(s): The ycjY-ymjD-ymjC-mpaA operon is derepressed under nutrient starvation for self-generation of amino acids, but it is repressed under high osmotic conditions for maintenance of the rigidity of the peptidoglycan (PG) sacculus, which provides mechanical strength to resist osmotic challenges Shimada T,2013
