Expression and purificationThe colonies were picked and yeast DNA was isolated (BMC,Biotechnology-2014) and expressed with inducer as methanol according to manufacturer’s protocol.
SDS-PAGE and silver staining was also used for the confirmation of expression.
His tag containing expressed protein was then purified with Ni-NTA column (QIAGEN,Germany) using affinity chromatography.
Protein was eluted with250 mM of imidazole containing elution buffer.
It was then dia-lyzed with MilliQ water and samples were collected and used for characterization.
