vector permitting positive selection for integration levansucrase
vector permitting visual detection of recombinants
Restriction digests of the clone give the following sizes (kb): ClaI--5.6, 0.40; ScaI--6.0; SmaI--6.0; AvaI--6.0.
The ClaI restriction recognition site located at bp 2093 is subject to dam methylation (gATCGAT) in its distribution host DH5alphaF'.
The ampR marker can easily be replaced by other antibiotic resistance-encoding cassettes by cloning into the unique ScaI site contained within the bla gene.
E. coli strains containing sacB are sucrose sensitive on LB medium + 5% sucrose. It is important to monitor sucrose sensitivity at each cloning step, as spontaneous mutations can accumulate during the process which then confer sucrose resistance.
Vector to construct mutants in Pseudomonas aeruginosa.
