Plasmid name: YDp-L (LMBP 3355)
|Price category:||Cat. 1 (cf. price list)|
|Status:||GeneCorner core plasmid|
(View with Genome Compiler)
|Cloned DNA:||Saccharomyces cerevisiae leucine 2 disruption cassette (LEU2)|
|Promoter:||Escherichia coli lac operon promoter|
|Selection marker:||Ampicillin (amp)
|Replicon:||Escherichia coli plasmid pMB1 origin|
|Host range:||Escherichia coli
Saccharomyces cerevisiae; leu2(-), integrative
|Parental clone:||pUC9HStop; pJH-L1|
|Further information:||The plasmid was constructed by inserting a 1601 bp (instead of 1613 bp as mentioned in Berben et al. (1991); personal communication Dr G. Berben) HpaI-AccI (filled in with Klenow DNA polymerase) fragment of pJH-L1, containing the S. cerevisiae LEU2 auxotrophically selectable marker gene, into the unique HindIII site (filled in with Klenow DNA polymerase) of pUC9HStop, a pUC9 derivative differing in the sequence of the multicloning site.
This is an integrative yeast plasmid designed for gene disruption purposes. The disruption cassette consists of the LEU2 gene, flanked by termination codons in all three reading frames and restriction sites. The termination codons prevent read-through from the remaining sequences of disrupted genes and those of the selectable disrupting fragment; in this way, possible artefactual phenotypic effects caused by fortuitous hybrid proteins are avoided.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727471.1.
The nucleotide sequences at the junctions were experimentally verified by Dr G. Berben prior to deposit at BCCM/GeneCorner.
