LOCUS       sequence-99421-e        7634 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Expresses both fragments of T7 RNAP split at position 179. The 
            N-terminal fragment is driven by PLac while the C-terminal fragment 
            is driven by PBAD. C-terminal fragment has the point mutations 
            N748D..
