BlcR D37V

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R1 (Part:BBa_K4361200) and F1.2 D37V (Part:BBa_K4361202). For this mutant, the aspartic acid in position 37 has been changed to valine by mutating the GAC codon to GTG.

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

  • A 50 > C, silent mutation
  • G 166 > T, resulting in substitution D56Y
  • G 237 > A, silent mutation
  • A 341 > C, resulting in substitution H114P
  • G 404 > T, resulting in substitution G135V
  • G 416 > T, resulting in substitution S139I

Sequencing data only contained this part's sequence up until and including nucleotide 421. All nucleotides after are presumed to be identical to those found in the original codon optimized BlcR, Part:BBa_K4361100.

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 2), a band was visible on the gel at the expected position, meaning that the production was successful for this mutant.
