1.1.1.3 | L200F |
site-directed mutagenesis, compared to mutant L200F, the double mutant shows 2 degree higher optimum temperature, 1.24 times higher activity, but the same pH optimum of pH 7.5 as mutant L200F. Both mutants L200F/D215K and L200F show good resistance to organic solvents and metal ions |

1.1.1.3 | more |
construction of a hybrid enzyme AKIII-HDHI+ by fusing a wild-type monofunctional aspartate kinase AKIII enzyme to the thrA2+ gene, encoding the homoserine dehydrogenase including the interface region of the wild-type bifunctional enzyme, the hybrid enzyme shows highly improved kinetic properties for homoserine dehydrogenase activity, and is not sensitive to L-threonine inhibition |

1.1.1.3 | more |
design of an artificial allosteric enzyme to sense an unnatural signal for a precise and dynamical control of fluxes of growth-essential but byproduct pathways in metabolic engineering of industrial microorganisms. The natural threonine binding sites of the enzyme are engineered to a lysine binding pocket. The reengineered enzyme only responds to lysine inhibition but not to threonine |
