CC -!- FUNCTION: Involved in protein export. The function of the beta subunit
CC is unknown, but it may be involved in stabilization of the trimeric
CC complex. {ECO:0000255|HAMAP-Rule:MF_00751}.
CC -!- SUBUNIT: Component of the protein translocase complex. Heterotrimer
CC consisting of alpha (SecY), beta (SecG) and gamma (SecE) subunits. Can
CC form oligomers of the heterotrimer. {ECO:0000255|HAMAP-Rule:MF_00751}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00751};
CC Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00751}.
CC -!- SIMILARITY: Belongs to the SEC61-beta family. {ECO:0000255|HAMAP-
CC Rule:MF_00751}.
