Part:BBa_K4361310

BlcR L66V

A mutant of the BlcR protein, created through site-directed mutagenesis with primers R3 (Part:BBa_K4361218) and F3.1 L66V (Part:BBa_K4361219). For this mutant, the leucine in position 66 has been changed to valine by mutating the CTC codon to GTG.

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 11), production in an E. coli based cell free system was not successful, no bands corresponding to BlcR were visible.

Figure 1. SDS PAGE showing the translation products of 20 different plasmids coding for BlcR mutants. 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. 11: L66V mutant.
