Part:BBa_K500001
lignin degradation 2
Yeast codon optimization , no terminator codon, from Phanerochaete chrysosporium. Synthetized by Geneart Mn peroxidases (MnP) are extracellular hemeproteins first discovered in the white-rot fungus Phanerochaete chrysosporium, and have been virtually detected in all lignin degrading fungi so far studied. The catalytic cycle of MnP is similar to that of other plant and fungal peroxidases

The iGEM Team Uppsala 2019 used this part to express MnP in Pichia pastoris. For this purpose, overhang PCR was performed and the gene was cloned into the pPICZαB vector by gibson assembly. In this vector, the gene is controlled by the AOX1-promoter and is cloned in-frame to an N-terminal α-secretion factor from S. cerevisiae. MnP was expressed in the X-33 wildtype strain of Pichia pastoris, where secretion was observed (Figure 1).

X-33 P. pastoris cells were transformed with pPICZαB_MnP and expression cultures were induced. Different fractions (pellet and supernatant samples / uninduced and induced cultures) from X-33 MnP expression culture were analysed on a 10 % SDS-PAGE stained with Coomassie Blue. Induction bands can be seen at a size of approximately 70 kDa in the induced samples for both pellet and supernatant fraction (red arrowhead), showing a secretion of MnP.
