Of special interest is the UPO from Marasmius rotula (MroUPO), which shows an exclusive repertoire of oxyfunctionalizations, including the terminal hydroxylation of alkanes, the alpha-oxidation of fatty acids and the C-C cleavage of corticosteroids. However, the lack of heterologous expression systems to perform directed evolution has impeded its engineering for practical applications. Here, we introduce a close ortholog of MroUPO, a UPO gene from Marasmius wettsteinii (MweUPO-1), that has a similar reaction profile to MroUPO and for which we have set up a directed evolution platform based on tandem-yeast expression. Recombinant MweUPO-1 was produced at high titers in the bioreactor (0.7 g/L) and characterized at the biochemical and atomic levels. The conjunction of soaking crystallographic experiments at a resolution up to 1.6 A together with the analysis of reaction patterns sheds light on the substrate preferences of this promiscuous biocatalyst.
