ccdB cell death gene

The CcdB protein, expressed by P1010, is lethal to most of the BioBrick cell strains, only DB3.1 is resistant.

P1010 is used in BioBrick assembly aid the process of moving a BioBrick part to a new plasmid. A target plasmid carrying P1010 is cut and mixed with the cut insert. Plasmids that recombine are selected against because they kill the cell that picks them up. P1010 is only provided as plasmid or in DB3.1 which is ccdB resistant.

-This is the part that is present inside the BioBricks insertion site in many of the pSB series of plasmids.  It is sufficient for positive selection even in pSB2* series plasmids  in the absence of inducer (~4-5 copies per cell).
-During assembly work at the Registry, we have found that point mutations (particularly frame shifts) occur at a high enough rate that several colonies will survive during a normal transformation. -Randy
