reactions known to be catalysed by other peroxidases ( e.g . thyroid peroxidase ( tpo ) and lactoperoxidase ) , such as inorganic iodide exchange for organic iodine in di-iodotyrosine ( dit ) and the de-iodination of thyroxine ( t4 ) , were also catalysed by the sonicated leucocyte suspension in the system used .
