Abstract | Bacteria have two routes for the l-methionine biosynthesis. In one route called the direct sulfuration pathway, acetylated l-homoserine is directly converted into l-homocysteine. The reaction using H Importance: In the present study, we can elucidate the pH-dependent regulation mechanism of the acidophilic OAHS. The acidophilic feature of the enzyme is caused by the introduction of an acidic residue to the neighborhood of the key acidic residue acting as a switch for the structural interconversion. The strategy may be useful in the field of protein engineering to change the optimal pH of the enzymes. In addition, this study may be useful for the development of antibacterial drugs because the l-methionine synthesis essential for bacteria is inhibited by the OAHS inhibitors. The compounds that can inhibit the interconversion between the open and closed forms of OAHS may become antibacterial drugs. |
