Substrates: enzymes involved in 4-chloronitrobenzene and nitrobenzene degradation are chloronitrobenzene nitroreductase, hydroxylaminobenzene mutase, 2-aminophenol 1,6-dioxygenase, and 2-aminomuconic semialdehyde dehydrogenase. When these enzymes are coupled in vitro, they sequentially catalyze the conversions of 4-chloronitrobenzene to 2-amino-5-chloromuconic acid and nitrobenzene to 2-aminomuconic acid Products: -

mutase in crude extracts is stable in the presence of 2% SDS, the partially purified enzyme loses 50% activity in the presence of 0.1% SDS after 30 sec
expression of enzyme plus nitrobenzene nitroreductase in Escherichia coli. Rapid and stoichiometric conversion of nitrobenzene to 2-aminophenol, of 2-nitroacetophenone to 2-amino-3-hydroxyacetophenone, and of 3-nitroacetophenone to 3-amino-2-hydroxyacetophenone, as well as further conversions. Final yields of aminophenols after extraction and recovery are over 64%
