Using superfolder green fluorescent protein for periplasmic protein localization studies

J Bacteriol. 2011 Sep;193(18):4984-7. doi: 10.1128/JB.00315-11. Epub 2011 Jul 15.

Abstract

Studies investigating the subcellular localization of periplasmic proteins have been hampered by problems with the export of green fluorescent protein (GFP). Here we show that a superfolding variant of GFP (sfGFP) is fluorescent following Sec-mediated transport and works best when the cotranslational branch of the pathway is employed.
