Name
2,4-dinitroanisole O-demethylase;
2,4-dinitroanisole ether hydrolase;
dnhA (gene name);
dnhB (gene name);
DNAN demethylase
Class
Hydrolases;
Acting on ether bonds;

Sysname
2,4-dinitroanisole methanol hydrolase
Reaction(IUBMB)
2,4-dinitroanisole + H2O = methanol + 2,4-dinitrophenol [RN:R11189]
Reaction(KEGG)
R11189
Substrate
2,4-dinitroanisole [CPD:C21159];
H2O [CPD:C00001]
Product
methanol [CPD:C00132];
2,4-dinitrophenol [CPD:C02496]
Comment
The enzyme, characterized from the bacterium Nocardioides sp. JS1661, is involved in the degradation of 2,4-dinitroanisole. Unlike other known O-demethylases, such as EC 1.14.99.15, 4-methoxybenzoate monooxygenase (O-demethylating), or EC 1.14.11.32, codeine 3-O-demethylase, it does not require oxygen or electron donors, and produces methanol rather than formaldehyde.
