Abstract

Cofactor maturation pathways such as the CCB system (system IV) for cytochrome c-heme attachment are conserved in all organisms performing oxygenic photosynthesis [ 1 ]. The CCB system consists of four proteins: CCB1-4. CCB2 and CCB4 are paralogues derived from a unique cyanobacterial ancestor [ 2 ]. Orthologues are conserved in higher plants [ 2 ].

This entry includes the plant CCB4.
