The primary catalytic action of the enzyme hen-white lysozyme is to hydrolyze β(1→4) glycosidic linkages | The primary catalytic action of the enzyme hen egg-white lysozyme is to hydrolyze β(1→4) glycosidic linkages found in bacterial cell walls.<ref>http://lysozyme.co.uk/</ref> More specifically, lysozyme hydrolyzes the linkages from ''N''-acetylmuramic acid to ''N''-acetylglucosamine which occur in peptidoglycans of the cell wall. The small 14.3 kD Hen egg-white lysozyme is one of the most widely studied lysozymes.<ref>Voet, Voet, and Pratt. Fundamentals of Biochemistry. 3 ed. John Wiley & Sons: 2008.</ref> | ||
