IUBMB Enzyme Nomenclature


Accepted name: 3,4-dihydroxyphenylalanine reductive deaminase

Reaction: L-dopa + NADH = 3,4-dihydroxyphenylpropanoate + NAD+ + NH3

Glossary: L-dopa = 3,4-dihydroxy-L-phenylalanine

Other name(s): reductive deaminase; DOPA-reductive deaminase; DOPARDA

Systematic name: 3,4-dihydroxy-L-phenylalanine ammonia-lyase (3,4-dihydroxyphenylpropanoate-forming)

Comments: Forms part of the L-phenylalanine-catabolism pathway in the anoxygenic phototrophic bacterium Rhodobacter sphaeroides OU5. NADPH is oxidized more slowly than NADH.
