pSC101ts temperature sensitive low copy origin of replication
BBa_K864051 is a pSC101ts origin of replication and is found in the pSB8*15 series of BioBrick vectors. This ori is identical to BBa_K864050, except for a mutation as described by [1]. This mutation changes one amino acid in the regulatory protein repA from alanine to valine, changing its binding properties.
Strains carrying the pSC101 plasmids can be grown stably at 30°C, but the plasmid will be lost at 42°C. For removing the plasmid, the strain can be streaked on a antibiotics-free LB agar plate and grown at 42° C overnight. Plasmid loss can be confirmed by streaking the new colonies on a plate with the relevant antibiotic. Transformants of pSB8 plasmids can, however, still recover from transformation at 37° without noticeable plasmid loss.
