Formate oxidase (FOx) from Aspergillus oryzae: one catalyst to promote H2O2‐dependent biocatalytic oxidation reactions
Tieves F, Willot SJ-P, van Schie MMCH, Rauch MCR, Younes SHH, Zhang W, Dong J, Gómez de Santos P, Robbins JM, Bommarius B, Alcalde M, Bommarius AS, Hollmann F
Angew. Chem. Int. Ed., 58: 7873-7877, 10.1002/anie.201902380
An increasing number of biocatalytic oxidation reactions rely on H2O2 as clean oxidant. The poor robustness of most enzymes towards H2O2, however, necessitates more efficient [...]

Description of a Non-Canonical Mn(II)-Oxidation Site in Peroxidases
Fernandez-Fueyo E, Davó-Siguero I, Almendral D, Linde D, Baratto MC, Pogni R, Romero A, Guallar V, Martínez AT
ACS-Catalysis, 8: 8386-8395
A dye-decolorizing peroxidase (DyP) from Pleurotus ostreatus (PosDyP4) catalyzes the oxidation of Mn2+ to Mn3+, in the presence of H2O2, with an efficiency similar to the [...]
