Introduction 2-HE(MET)3 Structural Overview Catalytic Triad Catalytic Triad Location Ligand Binding Site Figure 1 Mutations F243 F243 I243 F243W The original side chain is phenylalanine side chain, is located 3.6 Angstroms from the ligand. There are two main mutations isoleucine and tryptophan. Isoleucine is a smaller molecule and makes a tighter bond in the ligand, with the distance being 3.0 Angstrom. This allows for more efficient interactions with the ligand, likely improving substrate binding and catalytic efficiency. The other is tryptophan, which is a bulkier side chain, which does have a slightly shorter difference of 3.2 Angstroms, while being a larger side chain. The effect that is has is more based on that tryptophan is a nitrogen-containing aromatic ring, which offers new interactions with the substrate, which could also affect enzyme's binding and catalytic properties. These two mutations both lead to an increase in catalytic activity from the mutation, F243I had a 27.5% increase and F243W had an 17.5% increase, when compared to the wild-type variant. T96 T96 The original side chain is threonine and is mutated with a methionine. This is really a mutation that increases thermostability. The wild-type variant has a melting point of 84.7 degree Celsius. The mutation of methionine, is a larger, more hydrophobic side chain, and would contribute to stabilization of the protein's core by increasing hydrophobic interactions. The stronger internal interactions help the enzyme to maintain its folded structure more efficiently at elevated temperatures.
