1.13.11.4 | F159Y | site-directed mutagenesis | Pseudaminobacter salicylatoxidans |
1.13.11.4 | G106A | 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 | Pseudaminobacter salicylatoxidans |
