CC -!- FUNCTION: Possible low-potential cytochrome c. {ECO:0000305}.
CC -!- COFACTOR:
CC Name=heme c; Xref=ChEBI:CHEBI:61717; Evidence={ECO:0000305};
CC Note=Binds 1 heme c group covalently per subunit. {ECO:0000305};
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000305};
CC Peripheral membrane protein {ECO:0000305}; Lumenal side {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the cytochrome c family. PsbV subfamily.
CC {ECO:0000305}.
CC -!- CAUTION: In psbV2 it is not clear which residue serves as the second
CC axial ligand for the heme group. {ECO:0000305}.
