Hen egg-white lysozyme (HEWL) was the first enzyme to have its three-dimensional structure determined by X-ray diffraction techniques. A catalytic mechanism, featuring a long-lived oxocarbenium-ion intermediate, was proposed on the basis of model-building studies. The ‘Phillips’ mechanism is widely held as the paradigm for the catalytic mechanism of β-glycosidases that cleave glycosidic linkages with net retention of configuration of the anomeric centre. Studies with other retaining… CONTINUE READING
