Part:BBa_K4361305

BlcR A62I

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R7 (Part:BBa_K4361210) and F7.3 A62I (Part:BBa_K4361213). For this mutant, the alanine in position 62 has been changed to isoleucine by mutating the GCG codon to ATT.

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 6), a band was visible on the gel corresponding to BlcR, concluding that the production was successful for this mutant.

PURE reaction solution was supplemented with GreenLys and the synthesized proteins were imaged with Typhoon using a 488-nm laser. C: negative control with no plasmid. WT: positive control with expressed wildtype BlcR. 6: A62I mutant
