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 | Streptomyces roseochromogenus subsp. oscitans |
