BlcR A40V

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R4 (Part:BBa_K4361204) and F4.1 A40V (Part:BBa_K4361205). For this mutant, the alanine in position 40 has been changed to valine by mutating the GCG codon to GTG.

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

  • G 474 > T, silent mutation
  • T 529 > C, resulting in substitution F177L
  • G 606 > T, silent mutation
  • T 618 > A, silent mutation
  • G 648 > T, resulting in substitution E216D
  • T 681 > A, resulting in substitution E227D
  • G 742 > A, resulting in substitution E248A
  • A 745 > C, resulting in substitution K249Q

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