The bacterial Technology stringent response, triggered by nutritional deprivation, causes an accumulation of the signaling nucleotides pppGpp and ppGpp.We characterize the replication arrest that occurs during the stringent response in Escherichia coli.Wild type cells undergo a RelA-dependent arrest after treatment with serine hydroxamate to contai
