NOt to all enzymes. Cyanide has a high affinity for certain sulfur compounds. and for certain metallic complexes, particularly those containing cobalt and the trivalent form of iron (Fe3+).The 'cyanide ion' can rapidly combine with iron in cytochrome a3 (a component of the cytochrome aa3 or cytochrome oxidase complex in mitochrondria) to inhibit this enzyme, thus preventing intracellular oxygen utilization. The cell then utilizes anaerobic metabolism, creating excess lactic acid and a metabolic acidosis. Cyanide also has a high affinity for the ferric iron of methemoglobin and one therapeutic strategem induces the formation of methemoglobin to which cyanide preferentially binds.
