Abstract

Background: Lactoperoxidase plays a key role in host defense by oxidizing thiocyanate to the bactericidal agent hypothiocyanite. Results: Urate is a good substrate for lactoperoxidase and competes with thiocyanate for oxidation in vitro. Conclusion: Urate is a likely physiological substrate for lactoperoxidase. Significance: Urate may influence the bactericidal activity of lactoperoxidase. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.
