Peroxidase which is involved in maintaining the cuticle integrity in the hypodermis and pharynx (PubMed:30695063). It thus plays a role in conferring resistance against Gram-positive bacteria such as E.faecalis, S.aureus and C.diphtheriae, and yeast such as C.albicans (PubMed:24621828, PubMed:30695063). 2 a phenolic donor + H2O2 = 2 a phenolic radical donor + 2 H2O Expressed in the hypodermis and gland cells of the pharynx (PubMed:30695063). Specifically, there is low and transient expression from the distal bulb of the pharynx to the anterior of the buccal cavity (PubMed:30695063). Whole body expression levels increase upon entry into the dauer phase (PubMed:30695063). RNAi-mediated knockdown results in reduced survival in response to infection by E.faecalis. Belongs to the peroxidase family.
