Usage and Biology
We used an alcohol dehydrogenase(ADH) as part of our nootkatone pathway. The ADH we used for our project is from Pichia pastoris. It converts (+)-trans-nootkatol into (+)-nootkatone by oxidation, using NAD+ as a cofactor. A cofactor regeneration is not necessary in our case, because BM3, another enzyme of our nootkatone pathway, degrades NADH+H+ into NAD+. In nature ADH reduces or oxidizes alcohols to their specific aldehydes or ketones with help of NAD+.
This part additionally holds a PTS1 sequence for peroxisomal PEX5 import. For cytosolic expression please choose part: BBa_K2271115
Characterization
We verified the expression of ADH PTS1 via western blot. Therefore, we have a 3xFLAG-6xHis-Tag as a part in our plasmids, we can use for the antibodies. The estimated atomic mass of ADH PTS1 is 38kDa.
