1.14.13.243 A106E mutation in hydroxylase alpha-subunit TomA3, variant degrades its natural substrate toluene 63% faster than wild-type, with 50% 2-methylphenol, 25% 3-methylphenol, and 25% 4-methylphenol being formed. Whole cells expressing the A106E variant have two times better naphthalene-to-1-naphthol activity than the wild-type, and the regiospecificity of the A106E variant is unchanged, with 98% 1-naphthol formed -, 749647 1.14.13.243 A113H mutation in subunit TomA3. Mutant enzyme produces primarily isatin from indole -, 749719 1.14.13.243 A113I mutation in subunit TomA3. Mutant enzyme produces primarily indirubin from indole -, 749719 1.14.13.243 A113V mutation in subunit TomA3, colony turns blue. Mutant enzyme produces primarily indigo from indole -, 749719 1.14.13.243 V106A mutation in subunit TomA3, colony turns green. Mutant degrades trichloroethylene, 1,1-dichloroethylene, and trans-dichloroethylene more rapidly than wild-type. Whole cells expressing the mutant synthesize 1-naphthol six times faster than wild-type enzyme -, 750943 1.14.13.243 V106A/A113G mutation in subunit TomA3. Mutant enzyme produces primarily isatin from indole -, 749719 1.14.13.243 V106M mutation of the alpha-hydroxylase subunit TomA3, improves both rate and enantioselectivity. Mutant oxidizes methyl phenyl sulfide to the corresponding sulfoxide at a rate of 3.0 nmol/min/mg protein compared with 1.6 for the wild-type enzyme, and the enantiomeric excess (pro-S) increases from 51% for the wild type to 88% for the mutant -, 749648
