Biotechniques 16(2):194-196, 1994 is the description of the article I was
refering to.  I have constructed what I believe is a modification of this
vector with the insertion of the glycine kinker and thrombin cleavage site
from pGex-KG.  This vector however is still untested as it was only
recently done and I have not cloned in an insert protein and checked
cleavage.  When this is ready for prime time I would be happy to share. 
There also exists a vector constructed by Christopher Hugs at Washington
University (St. Louis, MO) which incorporates a factor Xa endopeptidase
site dowstream of GST.  This is driven by the Gal10 promoter and is has
several selection flavors e.g., Trp, His, Ura, and Leu.  These should be
available from ATCC.
