description: Cofactor maturation pathways such as the CCB system (system IV) for cytochrome c-heme attachment
  are conserved in all organisms performing oxygenic photosynthesis [[cite:PUB00075312]]. The CCB system
  consists of four protein, CCB1-4. The four CCBs are well conserved between green algae and plants [[cite:PUB00075315]].
