Unspecific peroxygenases (UPOs) have emerged as useful biocatalysts for the scalable and selective oxygenation of a large variety of organic molecules. UPOs have been divided into family I and family II enzymes, dependent upon sequence similarity and molecular weight, with family I being shorter in sequence. Here we report the characterisation and application of the family I UPO from Daldinia childiae ( Dch UPO). The enzyme was expressed in both Escherichia coli and Komagataella phaffii , yielding protein for kinetic and structural studies and biocatalytic application respectively. The structure of the enzyme revealed notable differences in the active site tunnel, compared with the well-studied family I artUPO, including F79 for V69 and F171 for I160. Notably, these differences were manifested in selectivity divergent from other UPOs when Dch UPO was applied to preparative biotransformations; for example, (-)-menthol was converted exclusively into cis -6-hydroxymenthol in contrast to artUPO, which gave exclusively the tertiary alcohol 2,8-menthanediol.
