Inc Ct226 is vital for FLI1 and LRRF1 recruitment to the chlamydial inclusion.

The obligate intracellular pathogen, , establishes an intracellular niche within a host membrane-derived vacuole called the chlamydial inclusion. From within this inclusion, orchestrates numerous host-pathogen interactions, in part, by utilizing a family of type III secreted effectors, termed inclusion membrane proteins (Incs). Incs are embedded within the inclusion membrane, and some function to recruit host proteins to the inclusion.

Proline transporters ProT and PutP are required for Staphylococcus aureus infection.

Proline acquired via specific transporters can serve as a proteinogenic substrate, carbon and nitrogen source, or osmolyte. Previous reports have documented that Staphylococcus aureus, a major community and nosocomial pathogen, encodes at least four proline transporters, PutP, OpuC, OpuD, and ProP. A combination of genetic approaches and 3H-proline transport assays reveal that a previously unrecognized transporter, ProT, in addition to PutP, are the major proline transporters in S.
