CC -!- SUBUNIT: May interact with Ccs1. case CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane; Multi- CC pass membrane protein. else case CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein. else CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Multi-pass membrane CC protein. end case CC -!- SIMILARITY: Belongs to the CcmF/CycK/Ccl1/NrfE/CcsA family.

Land plant cytochrome c6 is not functionally equivalent to that of C.reinhardtii or cyanobacteria. XX # Revision 1.11 2023/06/01 //
