Posttranscriptional and posttranslational regulation of the LEE. (A) Schematic of the LEE pathogenicity island. Functions of LEE-carried genes are indicated. (B to E) Posttranscriptional or posttranslational regulation of LEE-carried genes. Black lines represent interactions shown through genetic and biochemical data, whereas blue lines represent interactions relying solely on genetic data. Arrows indicate positive regulation, and blunted lines indicate negative regulation. For details, see the associated text.
