DEFINITION  Bacterial vector with a CloDF13 origin encoding tRNA genes for rare 
            Arg and Ile codons, for expressing a protein with a 6xHis-TEV leader
            plus a second untagged protein.

  TITLE     Direct Submission
COMMENT     There are two sites for ligation-independent cloning (LIC).
            
            To express a 6xHis-TEV-tagged protein, linearize with SspI and treat
            with T4 DNA polymerase plus dGTP.
            
            To express a second untagged protein, linearize with SmaI and treat 
            with T4 DNA polymerase plus dATP.
