RESUMO
The purification of (+)-cis-1(S),2(R)-dihydroxy-3-methylcyclohexa-3,5-diene dehydrogenase from cells of Pseudomonas putida grown with toluene as the sole source of carbon and energy is reported. The molecular weight of the enzyme is 104,000 at pH 9.7. The enzyme is composed of four apparently identical subunits with molecular weights of 27,000. The enzyme is specific for nicotinamide adenine dinucleotide and oxidizes a number of cis-dihydrodiols. Both enantiomers of a racemic mixture of cis-1,2-dihydroxyl-1,2-dihydronaphthalene dihydrodiol are oxidized by the enzyme. No enzymatic activity is observed with trans-1,2-dihydroxyl-1,2-dihydronaphthalene dihydrodiol.
