BlcR L38V

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R1 (Part:BBa_K4361200) and F1.3 L38V (Part:BBa_K4361203). For this mutant, the leucine in position 38 has been changed to valine by mutating the TTG codon to GTG.

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

  • G 9 > T, resulting in substitution Q3H
  • G 148 > T, resulting in a possible stop codon in position 50
  • G 156 > C, silent mutation
  • CGCG 198-201 > ATAT, resulting in substitution A67Y
  • A 364 > T, resulting in substitution T122S

Sequencing data only contained this part's sequence up until and including nucleotide 399. 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 this part) 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 20), a band was visible on the gel at the expected position, meaning that the production was successful for this mutant.
