Adaptor hierarchy: adaptors assemble in hierarchical manner to degrade proteins by ClpXP protease during cell cycle progression. Adaptor CpdR primes the protease for degradation of first class of substrates such as PdeA or McpA. The primed protease can the proteolyze second class of substrates such as TacA that are bound to scaffolding adaptor RcdA. Lastly, adaptor PopA binds to RcdA to bring third class of substrates such as CtrA to ClpXP for degradation
