The outer membranes of two independent colicin Ia-resistant mutants of Escherichia coli K-12 lack the colicin Ia receptor protein. Such mutants exhibit normal capacity for enterochelin (enterobactin)-mediated iron uptake. It is concluded that the colicin Ia receptor is not involved in iron-enterochelin uptake.
大肠杆菌K-12的两个独立的抗大肠菌素Ia突变体的外膜缺乏大肠菌素Ia受体蛋白。这类突变体在肠螯合素(肠杆菌素)介导的铁摄取方面表现出正常能力。由此得出结论,大肠菌素Ia受体不参与铁-肠螯合素的摄取。
