Protein
Protein translocase subunit SecE
Organism
Escherichia coli (strain K12)
Function
Essential subunit of the protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation. Overexpression of some hybrid proteins has been thought to jam the protein secretion apparatus resulting in cell death; while this may be true it also results in FtsH-mediated degradation of SecY.
Similarity
Belongs to the SecE/SEC61-gamma family.
