Part:BBa_K4361309

BlcR H63Y

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R7 (Part:BBa_K4361210) and F7.7 H63Y (Part:BBa_K4361217). For this mutant, the histidine in position 63 has been changed to tyrosine by mutating the CAC codon to TAT.

This mutant contains no nucleotide substitutions or indels outside of the targeted site.

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