UniProt functional annotation for Q5SHQ8



	UniProt functional annotation for Q5SHQ8

UniProt code: Q5SHQ8.

Organism: Thermus thermophilus (strain ATCC 27634 / DSM 579 / HB8).

Taxonomy: Bacteria; Deinococcus-Thermus; Deinococci; Thermales; Thermaceae; Thermus.

Function: The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

Subunit: Component of the Sec protein translocase complex. Heterotrimer consisting of SecY, SecE and SecG subunits. The heterotrimers can form oligomers, although 1 heterotrimer is thought to be able to translocate proteins. Interacts with the ribosome. Interacts with SecDF, and other proteins may be involved. Interacts with SecA. {ECO:0000269|PubMed:18923527}.

Subcellular location: Cell inner membrane {ECO:0000269|PubMed:18923527}; Multi-pass membrane protein {ECO:0000269|PubMed:18923527}.

Similarity: Belongs to the SecY/SEC61-alpha family. {ECO:0000305}.
