Abstract
Three independently isolated metK mutants have been shown to have leisions lying between speB and glc near 57 min on the Escherichia coli chromosome. Two deletions result in a lack of the metC gene product but neither extends into the metK glc region. The three metK mutations are recessive to the wild-type allele carried on the KLF16 episome.
摘要
已证明三个独立分离的metK突变体在大肠杆菌染色体上57分钟附近的speB和glc之间存在损伤。两个缺失导致metC基因产物缺失，但均未延伸到metK glc区域。这三个metK突变对KLF16附加体上携带的野生型等位基因是隐性的。
