Accepted name: (R)-dichlorprop dioxygenase (2-oxoglutarate)
Reaction: (1) (R)-2-(4-chloro-2-methylphenoxy)propanoate + 2-oxoglutarate + O2 = 4-chloro-2-methylphenol + pyruvate + succinate + CO2
(2) (R)-(2,4-dichlorophenoxy)propanoate + 2-oxoglutarate + O2 = 2,4-dichlorophenol + pyruvate + succinate + CO2
Glossary: (R)-2-(4-chloro-2-methylphenoxy)propanoate = (R)-mecoprop
(R)-(2,4-dichlorophenoxy)propanoate = (R)-dichlorprop
Other name(s): RdpA; α-ketoglutarate-dependent (R)-dichlorprop dioxygenase; (R)-phenoxypropionate/α-ketoglutarate-dioxygenase; 2-oxoglutarate-dependent (R)-dichlorprop dioxygenase; (R)-mecoprop dioxygenase; 2-oxoglutarate-dependent (R)-mecoprop dioxygenase
Systematic name: (R)-2-(4-chloro-2-methylphenoxy)propanoate,2-oxoglutarate:oxygen oxidoreductase (pyruvate-forming)
Comments: Fe2+-dependent enzyme. The enzymes from the Gram-negative bacteria Delftia acidovorans MC1 and Sphingomonas herbicidovorans MH are involved in the degradation of the (R)-enantiomer of the phenoxyalkanoic acid herbicides mecoprop and dichlorprop [1,2].
