3,4-dihydroxyphenylalanine reductive deaminase

The enzyme 3,4-dihydroxyphenylalanine reductive deaminase (EC 4.3.1.22, reductive deaminase, DOPA-reductive deaminase, DOPARDA; systematic name 3,4-dihydroxy- L -phenylalanine ammonia-lyase (3,4-dihydroxyphenylpropanoate-forming)) catalyses the following chemical reaction


 * L -dopa + 2 NADH $$\rightleftharpoons$$ 3,4-dihydroxyphenylpropanoate + 2 NAD+ + NH3

This enzyme participates in L -phenylalanine catabolism in the anaerobic phototrophic bacterium Rhodobacter sphaeroides OU5.
