N2 - The SecB, SecA, and SecY dependency of a small outer membrane lipoprotein in Escherichia coli, the bacteriocin release protein (BRP), was studied. The detrimental effect of BRP expression on the culture turbidity (quasi-lysis) was strongly reduced in the sec mutants. Immunoblotting and radioactive labeling experiments showed that the expression, membrane insertion, and processing of the BRP precursor are dependent on SecB, SecA, and SecY. Labeling experiments with hybrid BRP gene constructs revealed that the mature part of the BRP precursor and not its stable signal sequence is important for its SecB dependency.
