the three activities were found to be equally affected by monovalent anions known to be ligands to transition metals : the enzyme was reversibly inhibited by azide ( ki = 0.004mm ) , cyanate ( ki = 0.3 mm ) , thiocyanate ( ki = 1mm ) , nitrite ( ki = 0.4mm ) , nitrate ( ki = 6mm ) , chlorate ( ki = 3mm ) , fluoride ( ki = 5mm ) , and by chloride , bromide , iodide ( ki greater than 5mm ) .
