Extended information on the protein

• Kinetic information:

• Domains:
  • RapJ is 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 PhrC, 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.
