Family

Secretion monitor (IPR009502)

Short name: SecM

Family relationships

None.

Description

This family consists of several bacterial Secretion monitor precursor (SecM) proteins. SecM is known to regulate SecA expression by translational coupling of the secM secA operon. Translational pausing at a specific Pro residue 5 residues before the end of the protein may allow disruption of a mRNA repressor helix that normally suppresses secA translation initiation. The eubacterial protein secretion machinery consists of a number of soluble and membrane associated components. One critical element is SecA ATPase, which acts as a molecular motor to promote protein secretion at translocation sites that consist of SecYE, the SecA receptor, and SecG and SecDFyajC proteins, which regulate SecA membrane cycling [PMID: 10986266].
