LOCUS       sequence-433359-        4520 bp    DNA     circular SYN 15-DEC-2025
DEFINITION  Expresses DoubleCatcher-epsilon-Lock in bacterial cells. 
            DoubleCatcher-epsilon-Lock is a variant of DoubleCatcher in which 
            the orientation of each SpyCatcher003 moiety is locked via an 
            internal disulfide bond..
