LOCUS       sequence-204420-        4023 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  MIDAS Level-2 shuttle vector for assembling transcription units 
            (TUs) with forward orientation and (−) polarity. TUs assembled in 
            this vector are used for BsmBI-mediated Level-3 multigene assembly..
