The pi-histidine factor of Salmonella typhimurium: a demonstration that pi-histidine factor integrates into the chromosome.

abstract：:A total of 400 suppressible mutations have been isolated in the araC gene of Escherichia coli. Based on deletion mapping, growth patterns when suppressed, and intragenic recombination, 37 mutants have been determined to contain unique mutations. Rapid plate assays were developed to test for each of the three AraC prot...
