Reaction: butachlor + 2 reduced ferredoxin [iron-sulfur] cluster + O2 = 2-chloro-N-(2,6-diethylphenyl)acetamide + butyl formate + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O
Glossary: butachlor = N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)acetamide
acetochlor = N-(ethoxymethyl)-2-chloro-N-(2-ethyl,6-methylphenyl)acetamide
alachlor = N-(methoxymethyl)-2-chloro-N-(2,6-diethylphenyl)acetamide
Other name(s): cndA (gene name)
Systematic name: butachlor,ferredoxin:oxygen oxidoreductase (butyl formate-releasing)
Comments: The enzyme, characterized from the bacterium Sphingomonas sp. DC-6, initiates the degradation of several chloroacetanilide herbicides, including alachlor, acetochlor, and butachlor. The enzyme is a Rieske non-heme iron oxygenase, and requires a ferredoxin and EC 1.18.1.3, ferredoxin-NAD+ reductase, for activity.
