   2.5.1.111 | crystals are grown by hanging-drop vapor diffusion at 20 °C. Structure of of the apoenzyme, of CloQ complexed with 4-hydroxyphenylpyruvate, of mutant enzyme C215S complexed with 4-hydroxyphenylpyruvate and of the mutant enzyme R66S complexed with 4-hydroxyphenylpyruvate. Structure of CloQ complexed with 4-hydroxyphenylpyruvate reveals the formation of a covalent link between the substrate and Cys215 to yield a thiohemiketal species |

| 2.5.1.111 | molecular mechanics and hybrid quantum mechanics/molecular mechanics molecular dynamics simulations. Positively charged basic residues line the inside of the beta-barrel of CloQ to activate the diphosphate leaving group to replace the function of the Mg(2+) cofactor in other APTases. The effect of the replacement of the Mg(2+) cofactor with basic residues yields a similar activation barrier for prenylation to Mg(2+)-dependent APTases like NphB. The topology of the binding pocket for 4-hydroxyphenylpyruvate is important for selective prenylation at the ortho position of the ring. Methylation at this position alters the conformation of the substrate for O-prenylation at the phenol group |
