Halide peroxidase in tissues that interact with bacteria in the host squid Euprymna scolopes

AL Small, MJ McFall-Ngai, Journal of Cellular Biochemistry; PubMed

This Journal of Cellular Biochemistry scholarly article provides evidence to support the classification of the squid, Euprymna scolopes, peroxidase as a member of the family of halidependent peroxidases. Using three independent assays typically applied to the analysis of halide peroxidase enzymes, the activity of the squid enzyme was directly compared with that of human myeloperoxidase. In addition, tissue comparisons support a correlation between sustained interactions with bacteria (Vibrio fischeri) in the squid tissues and high levels of the peroxidase activity, immune cross-reactivity with an antibody to the peroxidase, and peroxidase mRNA.
