The structure of proteins can be affected by binding different ligands to them. Chicken egg white lysozyme is an important protein in protecting the egg from bacterial infections. N-Acetylmuramic acid (NAM) and N-Acetyl-D-glucosamine (NAG) are known amino sugars they are commonly found in bacterial cell walls. They are typically arranged in a regular, alternating pattern. NAM and NAG are present in both gram-positive and gram-negative cell walls, but are much more prominent in gram-positive cell walls. This research solved for the structure of chicken egg white lysozyme with and without NAM or NAG sugars.
