BlcR V68S

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R3 (Part:BBa_K4361218) and F3.9 V68S (Part:BBa_K4361227). For this mutant, the valine in position 68 has been changed to serine by mutating the GTG codon to AGC.

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 19), a protein band corresponding to the BlcR monomer is visible. Concluding that the production in an E. coli cell-free system 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. 19: V68S mutant.
