Regulatory ABC transporters

  • CydC-CydD: required for expression of cytochrome bd
  • EcsA-EcsB: regulation of the secretion apparatus and of intra-membrane proteolysis
  • FtsE-FtsX: activation of Spo0A and initiation of sporulation
  • YheH-YheI: involved in the signalling pathway to activate KinA at the onset of sporulation
  • SufC: required for the synthesis of Fe-S clusters
  • YydI-(YydJ-YydH): control of LiaR-LiaS activity
