CC   -!- FUNCTION: Heme chaperone required for the biogenesis of c-type
CC       cytochromes. Transiently binds heme delivered by CcmC and transfers the
CC       heme to apo-cytochromes in a process facilitated by CcmF and CcmH.
CC       {ECO:0000255|HAMAP-Rule:MF_01959}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01959}; Single-pass type II membrane protein
CC       {ECO:0000255|HAMAP-Rule:MF_01959}; Periplasmic side {ECO:0000255|HAMAP-
CC       Rule:MF_01959}.
CC   -!- SIMILARITY: Belongs to the CcmE/CycJ family. {ECO:0000255|HAMAP-
CC       Rule:MF_01959}.
