| Species: | Escherichia coli |
| Group: | K12 |
| Strain designation: | H12R8a |
| Accession number: | LMBP 4980 |
| Depositor: | Prof. Dr E. Remaut1 2 1 Department for Molecular Biomedical Research, VIB, Ghent, Belgium 2 Department of Biomedical Molecular Biology, Ghent University, Ghent, Belgium It was obtained from Dr A. Garen3 3 Department of Molecular Biology and Biophysics, Yale University, USA |
| Containment level: | This strain has been assigned the containment level Class 1 following the European Directive 2009/41/EC on the contained use of genetically modified organisms, and its updates (see also the Belgian risk group classification). |
| Medium: | LB-Lennox |
| Selection marker: | / |
| Temperature: | 37°C |
| Genotype: | Hfr garB10 fhuA22 phoA5(Am) ompF627(T2R) tyrT34(AS) fadL701(T2R) relA1 pitA10 spoT1 phoT-35 rrnB-2 mcrB1 creC510 (Source: CGSC 2597) |
| Phenotype: | phosphatase positive |
| Properties: | This strain carries the H12 amber mutation (TAG) in the phosphatase gene. This strain carries the supF suppressor (inserts tyrosine at the amber position) and is therefore capable of suppressing the H12 phosphatase nonsense mutation, as well as amber mutations in other genes. However, the efficiency of suppression may vary considerably depending on the sequence context of the amber codon. |
