counterselection levansucrase
suicide vector
vector permitting allelic exchange of cloned inserts
Comments
Restriction digests of the clone give the following sizes (kb): KpnI-- 6.55; XbaI-- 6.55; HindIII-- 3.2, 3.0.
The sacB1 allele is a variant of sacB with certain restriction sites removed by site directed mutagenesis. Expression of sacB confers sensitivity to sucrose.
The conditional R6K origin of replication requires that the pi protein be expressed in trans for plasmid maintenance.
One of four allelic exchange suicide vectors (ATCC 87691 - 87694) that provide both selection for chromosomal integration (ampR, cmlR, kanR or tetR) and counterselection for loss of vector DNA and the wild type allele.
Construct is suicide plasmid in any host not expressing pir.
Cloned inserts may be integrated into the host chromosome (a single recombination event) following electroporation and appropriate antibiotic selection.
Negative selection for sucrose sensitivity (sacB) selects for a second recombination event resulting in loss of vector DNA.
