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))[1] catalyses the following chemical reaction

L-dopa + 2 NADH 3,4-dihydroxyphenylpropanoate + 2 NAD+ + NH3

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