2.3.1.286 D101N the mutation affects the deacetylation activity of the enzyme -, 750904 2.3.1.286 D118N the mutant retains approximately 13% of the activity of the wild type protein 751549 2.3.1.286 E186A inactive 750253 2.3.1.286 E78A site-directed mutagenesis, mutation of the conserved catalytic amino acid prevents PhnO-dependent acetylation 757557 2.3.1.286 F70A site-directed mutagenesis, mutation of the conserved catalytic amino acid reduces YiaC-dependent acetylation compared to wild-type. Overexpression of YiaC YF70A inhibits cell migration similarly to overexpression of wild-type YiaC 757557 2.3.1.286 H135A inactive 750253 2.3.1.286 H135A the kcat/Km profile for the mutant exhibits no pH dependence over the range tested (pH 5.4-9.4), with kcat/Km values 2 orders of magnitude lower than wild type at high pH values 749880 2.3.1.286 H248Y inactive 739412 2.3.1.286 I117A inactive 751549 2.3.1.286 I117D inactive 751549
