OmpA + HIV protease cleavage site - GFP secretion system

Arabinose -> extracellular GFP

Upon addition of arabinose to the medium, the inducible Pbad promoter drives the expression of outer membrane protein A fused to a extracellular linker (ompA brick) followed by a cleavage site recognizable by HIV protease which is linked to GFP coding sequence.

If HIV protease is present in the medium, it will cut the cleavage site and GFP will be released from the outer membrane.

This part was used by [http://2012.igem.org/Team:UC_Chile 2012 UC Chile team] to secrete GFP. You can check the results HERE LINK!
