Abstract

A versatile plasmid vector was designed to direct the synthesis of recombinant proteins in either one of two forms that will be biotinylated in Escherichia coli with high efficiency at a single, unique site. The protein of interest can be produced with a peptide substrate for E. coli biotin holoenzyme synthetase (BirA) joined directly to its N terminus, or alternatively, as a fusion to the C terminus of a maltose-binding protein domain (MalE) with the peptide substrate on its N terminus. To maximize the yield of biotinylated protein, the vector is designed to express the substrate in a coupled translation arrangement with the enzyme.
