Part:BBa_K4361306

BlcR A62K

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R7 (Part:BBa_K4361210) and F7.4 A62K (Part:BBa_K4361214). For this mutant, the alanine in position 62 has been changed to lysine by mutating the GCG codon to AAA.

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

• A 800 deletion, resulting in a possible frameshift and extension of the protein

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