Part:BBa_K4361300

BlcR D37R

A mutant of the BlcR protein (Part:BBa_K4361100), created through site-directed mutagenesis with primers R1 (Part:BBa_K4361200) and F1.1 D37R (Part:BBa_K4361201). For this mutant, the aspartic acid in position 37 has been changed to arginine by mutating the GAC codon to CGC.

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

• G 763 > A, resulting in substitution E255K

Usage and Biology

The set of BlcR mutants (this part 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 1), it was concluded that the production was not successful due to the bands corresponding to BlcR being too poorly distinguishable.
