BlcR S61V

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R7 (Part:BBa_K4361210) and F7.1 S61V (Part:BBa_K4361211). For this mutant, the serine in position 61 has been changed to valine by mutating the AGT codon to GTG.

This mutant also contains the following nucleotide mutations outside of the targeted site:

  • C 705 > T, silent mutation

Usage and Biology

The set of BlcR mutants (Part:BBa_K4361300 through Part:BBa_K4361319) were expressed in a PURE system in the presence of GreenLys (fluorescent Cy2-labeled lysine). Samples were then run on an SDS PAGE gel (Figure 1.) to determine whether or not the protein was produced. For this mutant (lane 4), a protein band corresponding to the BlcR monomer is visible. Concluding that the production in an E. coli cell-free system was successful for this mutant.
