CC   -!- FUNCTION: Essential subunit of the Sec protein translocation channel
CC       SecYEG. Clamps together the 2 halves of SecY. May contact the channel
CC       plug during translocation. {ECO:0000255|HAMAP-Rule:MF_00422}.
CC   -!- SUBUNIT: Component of the Sec protein translocase complex. Heterotrimer
CC       consisting of SecY, SecE and SecG subunits. The heterotrimers can form
CC       oligomers, although 1 heterotrimer is thought to be able to translocate
CC       proteins. Interacts with the ribosome. Interacts with SecDF, and other
CC       proteins may be involved. Interacts with SecA. {ECO:0000255|HAMAP-
CC       Rule:MF_00422}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00422}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00422}.
CC   -!- SIMILARITY: Belongs to the SecE/SEC61-gamma family. {ECO:0000255|HAMAP-
CC       Rule:MF_00422}.
