CC   -!- FUNCTION: The SecYEG-SecDF-YajC-YidC holo-translocon (HTL) protein
CC       secretase/insertase is a supercomplex required for protein secretion,
CC       insertion of proteins into membranes, and assembly of membrane protein
CC       complexes. While the SecYEG complex is essential for assembly of a
CC       number of proteins and complexes, the SecDF-YajC-YidC subcomplex
CC       facilitates these functions. {ECO:0000250|UniProtKB:P0ADZ7}.
CC   -!- SUBUNIT: Part of the SecDF-YidC-YajC translocase complex. The SecDF-
CC       YidC-YajC translocase forms a supercomplex with SecYEG, called the
CC       holo-translocon (HTL). {ECO:0000250|UniProtKB:P0ADZ7}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000250|UniProtKB:P0ADZ7}; Single-pass membrane protein
CC       {ECO:0000250|UniProtKB:P0ADZ7}.
CC   -!- SIMILARITY: Belongs to the YajC family. {ECO:0000305}.
