Isolation and characterization of an Escherichia coli K-12 mutant defective in tyrosine- and phenylalanine-specific transport systems.
A mutant strain of Escherichia coli K-12 that is defective in both the tyrosine-specific and phenylalanine-specific transport systems was isolated. The defects in these systems were shown to be due to mutations in two distinct loci, tyrP and pheP, respectively.
