pKF117-DPB2 (=pKF120) intergrative plasmid into DPB2 locus; the DPB2 allele were introduced into the chromosome by transplacement; the pKF117 integrative vector containing DPB2 allele with its natural promotor and terminator was linearized at unique BamHI and XbaI sites positioned between promotor DPB2 and an additional fragment of the DPB2 terminator. The linearized plasmid was transformed into strain ΔI(-2)I-7B-YUNI300 msh6::hisG(no.4010D) Transformants were selected for uracil prototrophy on plates, which were incubated at 23ºC for up to 10 days. To confirm the integration into DPB2 chromosomal locus the genomic DNA of the isolated integrants was isolated and used as a template in a PCR reaction with primers: 5'-TGTAAAACGACGGCCAGT–3' ( 21-M13 universal primer) and 5'-GAATACTGGCTTACCGAG-3', which recognized the vector sequence and the chromosomal sequence downstream of DPB2, respectively, generating a 1361 bp band in case of integration into the aimed locus. |
| Właściwości szczepu/komentarz: |
strain grows well at 23-37oC; strain exhibits mutator phenotype; mutation frequencies can be measured at different genetic loci; trp1-289,ade2-1 allow to measure base substitution; his7-2 lys2-ΔGG2899-2900 allow to measure frameshift mutations, CAN1 |
