Abstract:Another round of saturation mutagenesis on active site residues with 1-K31 as parent followed by random mutagenesis yielded the mutant 3-R21. Whole cell activity of 3-R21 for AN, 24DMA and 2IPA were 27.7, 9.8, and 12 nmol/min/mg protein respectively. The activities of 3-R21 for AN, 24DMA and 2IPA were improved by 8.9, 98.0, and 2.0-fold respectively over its parent 1-K31. In particular, the activity of the final mutant 3-R21 was improved by 3.5-fold over the WT AtdA enzyme. Overall, mutant 3-R21 had three mutations---V205A, 1248L, and S404C.
