pGEX-KG is a derivative of the pGEX-2T orginally developed by Smith and
Johnson (Gene, 67:31-40 ). This vector incorporates a glycine
kinker/spacer between the thrombin cleavage site and the polylinker. The
polylinker in this vector has also been expanded. The origin of
replication is pBr322. Details of its construction are found in Guan and
Dixon (Analytical Biochemistry, 192:262-267 ). Hope this helps!
