Reaction Conditions:
with ascorbic acid in aq. phosphate buffer at 25;
Steps:
                     2.5. Reaction to produce 3,4-dihydroxyphenylacetic acid (DHPAA) from 4-hydroxyphenylacetic acid (HPAA)
A typical reaction was started by addition of 15.0 mg of tyrosinaseCLEAs into 20.0 mL of Na phosphate buffer (50 mM, pH 6.0) containing10.0mM HPAA and 15.0mM L-ascorbic acid in a 50 mL conical flask,which was placed in a shaking incubator with agitation of 200 rpm at25 °C. Periodically, a 0.15 mL sample was taken which was then fourtimes diluted with the buffer before subjected to HPLC analysis as describedbelow.
