Haloperoxidase (original) (raw)
Haloperoxidases are peroxidases that are able to mediate the oxidation of halides by hydrogen peroxide. Both halides and hydrogen peroxide are widely available in the environment. The Nernst equation shows that hydrogen peroxide can oxidize chloride (E°= 1.36 V), bromide (E°= 1.09 V) and iodide (E°= 0.536 V) from a thermodynamic perspective under natural conditions, i.e., a temperature range of about 0–30 °C and a pH ranging from about 3 (humic soil layer) to about 8 (sea water). Fluoride (E°= 2.87 V) cannot be oxidized by hydrogen peroxide.

Zowel halogeniden en waterstofperoxide komen in het milieu voor. Met de wet van Nernst is uit te rekenen dat waterstofperoxide chloride (E°= 1,36 V), bromide (E°= 1,09 V) en jodide (E°= 0,536 V) onder natuurlijke omstandigheden, bijvoorbeeld in een temperatuurbereik van 0-30 °C en een pH van 3 (humus) tot 8 (zeewater) kan oxideren. Fluoride (E°= 2,87 V) kan niet onder natuurlijke omstandigheden worden geoxideerd. De onderstaande tabel classificeert de haloperoxidasen naar de halogeniden van welke ze de oxidatie kunnen katalyseren. (nl) |
