Mossbauer studies of the ferryl, ferrous and ferric states of dehaloperoxidase from A. ornata

JOURNAL OF INORGANIC BIOCHEMISTRY, 234.

By: C. Popescu*, T. Dinh*, H. Chen*, D. Miller*, A. Washburn*, A. McGuire n, R. Dumarieh n, J. D'Antonio n, R. Ghiladi n

author keywords: Mossbauer spectroscopy; Peroxidase; Heme enzyme; Ferryl; Globin
MeSH headings : Animals; Ferric Compounds / chemistry; Heme / chemistry; Hemoglobins / chemistry; Hydrogen Peroxide / chemistry; Iron / chemistry; Myoglobin / chemistry; Peroxidases / metabolism; Polychaeta; Spectroscopy, Mossbauer
TL;DR: The isomer shift and quadrupole splitting of DHP in the four states studied are expectedly similar to both peroxidases and to myoglobin, and differences in electronic structure between DHP and other heme proteins and enzyme are observed in the high-field Mössbauer spectra of the ferric state, which show pH-dependent zero-field splittings suggesting a heme site in which the ligand field strength at the iron ion is tuned by pH.

TL;DR: The marine globin dehaloperoxidase‐hemoglobin (DHP) from Amphitrite ornata was found to catalyze the H2O2‐dependent oxidation of monohaloindoles, a previously unreported class of substrate for DHP, and non‐enzymatic and anaerobic controls suggest a novel oxidase activity for D HP.
