Figure 4

The amino acid residues for AdoMet binding and hypothetical reaction mechanism of TrmB. (A) The amino acid residues (E47, Y95, R108, T165 and Y167) involved in AdoMet binding (orange) are indicated on the catalytic domain of B. subtilis TrmB structure (PDB: 2FCA). The hypothetical catalytic center (grey shading), Asp133 (red) and the other important amino acid residues (D74, D97 and T132; blue) are highlighted. (B) Hypothetical reaction mechanism of eubacterial TrmB proteins is drawn.
