3,4-dihydroxyphenylalanine oxidative deaminase explained

3,4-dihydroxyphenylalanine oxidative deaminase
Ec Number:	1.13.12.15

3,4-dihydroxyphenylalanine oxidative deaminase (3,4-dihydroxy-L-phenylalanine: oxidative deaminase, oxidative deaminase, DOPA oxidative deaminase, DOPAODA) is an enzyme with systematic name 3,4-dihydroxy-L-phenylalanine:oxygen oxidoreductase (deaminating).^[1] This enzyme catalyses the following chemical reaction

2 L-dopa + O₂

\rightleftharpoons 2 3,4-dihydroxyphenylpyruvate + 2 NH₃

This enzyme is one of the three enzymes involved in L-dopa (3,4-dihydroxy-L-phenylalanine) catabolism in the bacterium Rubrivivax benzoatilyticus.
