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.
分离出了一株大肠杆菌K-12突变株,该突变株在酪氨酸特异性转运系统和苯丙氨酸特异性转运系统中均存在缺陷。结果表明,这些系统中的缺陷分别是由两个不同位点tyrP和pheP的突变引起的。
