Abstract

We identified four outer membrane proteins (protein a and the iron-regulated proteins 74K, 81K, and 83K) present in reduced amounts of Escherichia coli K-12 perA strains. A comparison of the levels of enterochelin with the levels of 74K, 81K, and 83K suggested that perA acts posttranscriptionally.

摘要

我们鉴定出了四种外膜蛋白（蛋白a以及铁调节蛋白74K、81K和83K），它们在大肠杆菌K-12 perA菌株中的含量有所减少。对肠螯合素水平与74K、81K和83K水平的比较表明，perA在转录后起作用。
