Abstract excerpt

pheV, one of the genes that code for tRNA(Phe), was deleted from the chromosome of a strain of Escherichia coli K-12. As a consequence of this mutation, expression of pheA, the gene for chorismate mutase P-prephenate dehydratase, the first enzyme in the terminal pathway of phenylalanine biosynthesis, was derepressed. Similar derepression of pheA has been reported in pheR mutants of E. coli K-12 (J. Gowrishankar...
