These proteins contain the so-called tetratricopeptide repeats (TPRs) protein-protein interaction module. They control the phosphorelay for sporulation initiation by dephosphorylating Spo0F-P or they inhibit transcription factors by protein-protein interaction (without affecting phosphorylation). The activity of these proteins can be controlled by small peptides that are expressed as precursors, exported, and re-imported into the cell.
The RAP phosphatases are made up of the C-terminal tetratricopeptide repeat (TPR) domain that is connected by a flexible helix containing linker to the N-terminal 3-helix bundle. Upon binding of the regulating peptide, the 3-helix bundle and the linker helix undergo a conformational change to form a TPR-like fold that merges with the existing C-terminal TPR domain. PubMed
