Part of the accessory SecA2/SecY2 system specifically required for correct glycosylation and export of Fap1, a serine-rich fimbrial adhesin. Potentially the central subunit of a protein translocation channel. 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 (Potential). Part of the accessory SecA2/SecY2 protein translocation apparatus required to export cell wall proteins. No effect on general protein secretion. Decreases the extent of glycosylation of serine-rich fimbrial adhesin Fap1, but the protein is still found on the cell surface. The partially glycosylated Fap1 is larger than the wild-type protein. Belongs to the SecY/SEC61-alpha family. SecY2 subfamily.
