Reduction in three iron-regulated outer membrane proteins and protein a by the Escherichia coli K-12 perA mutation.
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.
