#Unit 2. Cellular Organization

Lysozyme is an enzyme that destroys bacterial cell walls. It does so by hydrolyzing the β(1→4) glycosidic linkages from N- acetylmuramic acid (NAM or MurNAc) to N- acetylglucosamine (NAG or GlcNAc) in cell wall peptidoglycans. The only functional groups in the immediate vicinity of lysozyme’s reactive center that have the required catalytic properties are the side chains of Glu 35 and Asp 52.
a- Glu perform reaction in its protonated state and Asp perform reaction in its deprotonated state. 
b- Glu perform reaction in its deprotonated state and Asp perform reaction in its protonated state. 
c- both in its protonated form
d- both in its deprotonated form
