Maps of the 13 C. glutamicum genome loci containing genes for two-component signal transduction systems. The different colors indicate different functions of the encoded proteins or different localizations of proteins with unknown functions. The numbers are derived from GenBank accession no. BX927147 (13). put., putative; Me, metal; assoc., associated; biosynth., biosynthesis; mech.-sens., mechano-sensitive; CoA, coenzyme A; transp., transporter.
