UniProt annotation for SECG_METJA » Preprotein translocase subunit SecG
FUNCTION: Subunit of the protein translocation channel SecYEG. The function of the beta subunit is unknown, but it may be involved in stabilization of the trimeric complex.

SUBUNIT: Component of the Sec protein translocase complex. Heterotrimer consisting of alpha (SecY), beta (SecG) and gamma (SecE) subunits. The heterotrimers can form oligomers, although 1 heterotrimer is thought to be able to translocate proteins. Interacts with the ribosome. May interact with SecDF, and other proteins may be involved.
