The regulation of catabolite repression of beta-galactosidase has been studied in Escherichia coli mutants deleted for the adenyl cyclase gene (cya delta), and thus unable to synthesize cyclic AMP. It has been found that, provided a second mutation occurs either in the crp gene coding for the catabo
