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}.
