Abstract excerpt
The phenotype of Escherichia coli appR pleiotropic mutants has been compared with that of mutants in the katF gene, which lies in the same region and controls expression of catalase HPII (katE) and exonuclease III (xth). All the described characters of appR mutants--reduced pH 2.5 acid phosphatase level, overexpression of alkaline phosphatase and ability of crp or cya mutants to utilize some CAP + cAMP-dependent...
