AOX1-Kozak-FLO10-pelA-His tag-AOX1 Terminator
The FLO10 gene of S. cerevisiae, encoding invertase was designed to codon preference of P. pastoris excluding the sequence of the N-terminal pre-pro-sequence signal peptide and His-tag in the C terminus. pelA can catalyze pectin.
Characterization
This is a four section for degrade and transfer pectin part.
DNA Gel Electrophoretic
After we link FLO10 and pelA successfully, we run the PCR with an intention to confirm the expression of pelA. As the figure shows, we get the genetic stripe about 1092 bp which means the PCR is successful. Electro-transformation to Pichia pastoris was all succeeded.
Enzyme Activity
The enzyme activity of the pelA group is obtained by titration and daily measurement of enzyme activity.
Pectin is a hydrophilic polysaccharide substance present in the interstitial of plant cells. It is stable in acidic medium and insoluble in ethanol. It is a natural polymer compound. We understand that pectinase measures enzyme activity has a nationally standardized experimental procedure, so we have adopted the standard titration scheme given by the state. [3]
