Control of bacterial transcription, translation and replication by (p)ppGpp.

abstract：:Wild Escherichia coli are superbly adapted to survive in the intestines of their mammalian hosts and in the environment. E. coli K12 derivative (MG1655) encodes 4288 potential genes that provide the background genetic framework of this species. Particular E. coli clonal types encode additional chromosomal and extrachr...
