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. SecY
CC is required to insert newly synthesized SecY into the inner membrane.
CC Overexpression of some hybrid proteins has been thought to jam the
CC protein secretion apparatus resulting in cell death; while this may be
CC true, overexpression also results in FtsH-mediated degradation of SecY.
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-YajC and
CC YidC; YidC interacts with nascent inner membrane proteins after SecY.
CC The SecDF-YidC-YajC translocase forms a supercomplex with SecYEG,
CC called the holo-translocon (HTL) (PubMed:27435098). The stoichiometry
CC of the super complex may be SecYEG:YidC:SecDF 4:3:1, YajC is in the
CC reconstituted complex (with SecDF) but as no antibody is available it
CC could not be quantified (PubMed:27435098). SecY probably contacts the
CC 23S rRNA and possibly also ribosomal protein L23 during ribosome
CC docking. A single SecY molecule forms the translocating pore, although
CC interaction with SecA may require oligomers.
CC {ECO:0000269|PubMed:11415986, ECO:0000269|PubMed:17418789,
CC ECO:0000269|PubMed:27435098}.

CC P0AGA2; P0AG99: secG; NbExp=3; IntAct=EBI-761422, EBI-6404248;
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC -!- PTM: SecY that is not part of the protein translocation apparatus is
CC degraded by FtsH. Also degraded by FtsH when the SecYEG complex is
CC jammed, or upon treatment with antibiotics that block translation
CC elongation such as chloramphenicol.
CC -!- SIMILARITY: Belongs to the SecY/SEC61-alpha family. {ECO:0000305}.
