pH-dependent fluoride inhibition of catalase activity

Oral Microbiology and Immunology
E A Thibodeau, T F Keefe

Abstract

The inhibitory effects of fluoride on several catalases were examined over a range of pH conditions. Preparations of bovine-liver catalase were sensitive to fluoride under acidic conditions. Catalase activity associated with whole-cell preparations of Actinomyces viscosus NP 311A remained relatively constant between pH 3.0 and 8.0 and was inhibited by fluoride in a pH-dependent manner. Fluoride was also observed to enhance hydrogen peroxide killing of A. viscosus NP 311A under acidic pH conditions. Results suggest that some catalase enzymes, including those associated with common plaque bacteria, may be inhibited by fluoride in a pH-dependent manner.

Actinomycosis

Actinomycosis is a rare, chronic, and slowly progressive granulomatous disease caused by filamentous Gram positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). The disease is characterised by the formation of painful abscesses in the mouth, lungs,breast or gastrointestinal tract. Discover the latest research on actinomycosis here.
