Species:Escherichia coli
Group:K12
Strain designation:SG4044
Accession number:LMBP 670
Depositor:Prof.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 S.Gottesman3
3 Laboratory of Molecular Biology,NCI,NIH,Bethesda,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:lon-100Δ(gal-pgl)324 lac thi rpsL
Phenotype:StrR Lon-non-mucoid
Properties:-
Further information:The Lon protease plays a major role in the proteolytic machinery of E.coli.Lon mutants are highly pleioptropic and produce mucoid colonies that are difficult to handle.The(gal-pgl)deletion eliminates mucoidy and restores normal colony morphology.
Lon mutants may be useful in stabilizing heterologous proteins expressed in E.coli(see e.g.Remaut et al.,1983).
