A Novel Unspecific Peroxygenase from Galatian marginata for Biocatalytic Oxyfunctionalization Reactions

Unspecific peroxygenases (UPOs, EC 1.11.2.1) are promising oxyfunctionalization catalysts because of their unique stereoselectivity. However, so far only a few UPOs have been reported. In this study, gene mining was used to identify a gene from Galerina marginata that coded for a novel UPO (GmaUPO). GmaUPO was expressed in Pichia pastoris X...

How To Break the Janus Effect of H ₂ O ₂ in Biocatalysis? Understanding Inactivation Mechanisms To Generate more Robust Enzymes

H ₂ O ₂ , is an attractive oxidant for synthetic chemistry, especially if activated as percarboxylic acid. H ₂ O ₂ , however, is also a potent inactivator of enzymes. Protein engineering efforts to improve enzyme resistance against H ₂ O ₂ in the past have mostly focused on...
