Expression construct AAO-2A-eGFP
Expression circuit for aryl-alcohol oxidase (AAO) and eGFP in Pichia pastoris. AAO will be secreted due to the addition of the α-factor secretion signal and eGFP will remain in the cell. The 2A-selfcleaving peptide will lead to cleavage of the polypeptide, achieving separation of AAO from eGFP.

Results
The constructs was transformed in Pichia pastoris and colonies were screened on BMMY-agar plates (contain methanol for induction of expression) (Figure 1). Visualisation of eGFP by excitation with blue light shows eGFP positive clones. Due to the nature of the circuit, those clones also express AAO.
Figure 1: eGFP coexpression
Transformed P. pastoris cells coexpressing eGFP and AAO were screened on a BMMY agar plate. eGFP is visible for two of the restreaked colonies, in the middle. Picture was taken on a blue light box under an orange filter after 4 days of incubation at 28 °C with daily addition of 50 µL methanol on the plate lid.
