N-Acetyl L-Tyrosine

This page depicts the oxidation of N-Acetyl L-Tyrosine (NAT) by Horse Radish Peroxidase (HRP)

The Dioxane Conundrum

The following two graphs depict the difference in reaction when dioxane is present and when it is not.

Figure 1: NAT oxidation in solution with dioxane and reacted with H2O2 and HRP 6/5/16. This graph shows the dioxane in the solution inhibiting the reaction completely.

Figure 2: 2mM NAT oxidation without dioxane and reacted with 2mM H2O2 and HRP in a beaker 6/5/16

Beaker Reaction vs. Immobilized Enzyme Bio-Reactor

Utilizing the immobilization technique in a bio-reactor allows for the control of the rate of flow of the reaction. This makes the peaks in the products much more defined.

Figure 3: 2mM NAT oxidation without dioxane and reacted with 1mM H2O2 using the Immobilized Enzyme technique 6/9/16
