site-directed mutagenesis, in contrast to the wild-type enzyme, mutant G106A oxidizes only gentisate, while 1-hydroxy-2-naphthoate and salicylate are not converted. The mutant shows slightly decreased activity with salicylate, but shows a higher affinity to this substratecompared to the wild-type. Salicylate is coordinated in the G106A variant with the catalytically active Fe(II) ion in an unusual and unproductive manner because of the inability of salicylate to displace a hydrogen bond that is formed between Trp104 and Asp174 in the G106A variant

gene narI, DNA and amino acid sequence determination and analysis of the gentisate catabolic gene cluster. Among the 13 complete open reading frames deduced from this fragment, three narIKL encode the enzymes involved in the reactions of gentisate catabolism, of these, NarI is gentisate 1,2-dioxygenase which converts gentisate to maleylpyruvate. Genes narI, narK, and narL genes are transcribed as a single operon only in the presence of naphthalene. Sequence comparisons, overview. Expression in Escherichia coli strain Rosetta (DE3) pLysS
genes nagI1, nagI2, and nagI3, the latter encoded in the third cluster, nagl3 is polycistronic and is expressed at a relatively high level, genetic organization, DNA and amino acid sequence determination and analysis, real-time RT-PCR for gene expression analysis of genes nagI1, nagI2 and nagI3 and the third catabolic gene cluster, overview. Overexpression of all three genes in Escherichia coli strain BL21(DE3). The transformation efficiency of the pET21bnagI1 ligation product is very low compared with that of the nagI2 and nagI3 genes
