Pathway Microbial metabolism in diverse environments (stm01120 )
Nitrotoluene degradation (stm00633 )
Function This enzyme catalyzes the reduction of nitroaromatic compounds using NADPH, and has a broad electron acceptor specificity. Moreover, it reduces nitrofurazone by a ping-pong bi-bi mechanism possibly to generate a two-electron transfer product.
