Description
This part encodes for the AOx1 protein from Pichia Pastoris.
Alcohol oxidase is an oligomeric enzyme with eight identical sub-units, containing a bound molecule cofactor, flavin adenine dinucleotide (FAD). It is produced by methylotrophic yeasts (such us our chosen??Pichia) located and assembled in peroxisomes during growth on methanol (1). AOx is implicated in the methanol oxidation pathway in yeasts, however it can also oxidise other short-chain alcohols, such as ethanol, propanol or butanol (2).
AOX is thus responsible for the oxidation of primary alcohols to the equivalent aldehyde, using molecular oxygen (O2) as the electron acceptor, creating Hydrogen Peroxide (H202) as a by-product.

Notes
The part is designed with an NdeI restriction site between the prefix and the start of the AOx gene. This is because we wanted to assemble the gene in protein expression pET vectors, which normally contain an NdeI restriction site after the Ribosome Binding Site.
