We report here the characterization of the catalytic component (ISP NAR ) of a new naphthalene dioxygenase from Rhodococcus sp. strain NCIMB12038. The genes encoding the two subunits of ISP NAR are not homologous to their previously characterized counterparts in Pseudomonas . The deduced amino acid sequences have only 33 and 29% identity with the corresponding subunits in Pseudomonas putida NCIB 9816-4, for which the tertiary structure has been reported.
