Part:BBa_K4361300

BlcR D37R

A mutant of the BlcR protein (Part:BBa_K4361100), created through site-directed mutagenesis with primers R1 (Part:BBa_K4361200) and F1.1 D37R (Part:BBa_K4361201). For this mutant, the aspartic acid in position 37 has been changed to arginine by mutating the GAC codon to CGC.

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

• G 763 > A, resulting in substitution E255K

Experimental results

The set of BlcR mutants (this part 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 1), BlcR mutant D37R could not be succesfully produced in the PURE system.

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. 1: D37R mutant.
