Regulation of T1F expression in Salmonella. Proteins directly involved in T1F expression are represented as ovals. Proteins involved in activation of T3SS (HilE, HilA) are represented as pentagons. All proteins encoded by the fim operon, including three major regulatory proteins, FimZ, FimY, and FimW are colored according to the scheme in the operon figure (Figure 1). Red arrows indicate direct promoter activation. Black arrows indicate another type of activation (not specified).
