The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity: binds ImmR and inhibits its activity, this results in induction of the genes for the transfer of the mobile genetic element ICEBs1 PubMed

• Protein family: RAP family (according to Swiss-Prot)

• Paralogous protein(s):

Extended information on the protein

• Kinetic information:

• Domains:

• Modification:

• Cofactor(s):

• Effectors of protein activity: binding of PhrI indicates that neighbour cells do already contain the genetic element ICEBs1, this results in inactivation of RapI PubMed

• Interactions: RapI-ImmR PubMed, RapI-PhrI PubMed
