CC -!- FUNCTION: The central subunit of the protein translocation channel
CC SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two
CC domains form a lateral gate at the front which open onto the bilayer
CC between TMs 2 and 7, and are clamped together by SecE at the back. The
CC channel is closed by both a pore ring composed of hydrophobic SecY
CC resides and a short helix (helix 2A) on the extracellular side of the
CC membrane which forms a plug. The plug probably moves laterally to allow
CC the channel to open. The ring and the pore may move independently.
CC {ECO:0000256|HAMAP-Rule:MF_01465, ECO:0000256|RuleBase:RU000537}.
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:0000256|HAMAP-
CC Rule:MF_01465}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_01465};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_01465}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141, ECO:0000256|RuleBase:RU003484}; Multi-
CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141,
CC ECO:0000256|RuleBase:RU003484}.
CC -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family.
CC {ECO:0000256|ARBA:ARBA00005751, ECO:0000256|HAMAP-Rule:MF_01465,
CC ECO:0000256|RuleBase:RU004349}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
