Enzyme Function FUNCTION: Displays both high peroxidase and manganese peroxidase activity. Is likely involved in lignin degradation. Also has a Mn-dependent oxidase mode of action that expands its substrate scope in vitro; is thus able to catalyze the O(2)- and Mn-dependent oxidative decarboxylation of 4-methoxymandelate to anisaldehyde. {ECO:0000269|PubMed:23054399}.
Temperature Dependency
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 4.5 for the H(2)O(2)-dependent oxidation of Reactive Blue 5, and 5.0 for the O(2)-dependent oxidation of 4-methoxymandelate. {ECO:0000269|PubMed:23054399};

Subcellular Location SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:23054399}. Note=Although no signal sequence is found, the secretory machinery for actinomycetes is not fully characterized, and the low pH optimum for DyP2 along with the observation that many DyPs have been isolated from the secreted protein fraction imply that DyP2 could be secreted and still possibly play a role in extracellular oxidation chemistry (PubMed:23054399).
