1.21.1.1 | 2-iodophenol + NADP+ + iodide |
2-iodophenol binds very weakly to the enzyme and is dehalogenated with a catalytic efficiency that is more than 4 orders of magnitude lower than that for 3-iodo-L-tyrosine |

1.21.1.1 | 3,5-diiodo-L-tyrosine + dithionite |
solubilized enzyme preparations are active with dithionite, but not with NADPH. Particle-bound enzyme uses both dithionite and NADPH. At concentrations of substrate below 1 microM, 3,5-diiodo-L-tyrosine is more rapidly deiodinated than 3-iodo-L-tyrosine, which is reversed at concentrations greater than 5 microM |
