As seen above, lysozyme works by hydrolyzing the glycosidic bond, distorting the bond between the N-acetylglucosamine sugar and the N-acetylmuramic acid sugar. This produces a glycosyl enzyme intermediate, which reacts with a water molecule to produce the product and the unchanged enzyme. | As seen above, lysozyme works by hydrolyzing the glycosidic bond, distorting the bond between the N-acetylglucosamine sugar and the N-acetylmuramic acid sugar.

Lysozyme is best inhibited by small saccharides which act competitively with the natural substrate. The smaller saccharides will bind to the first three binding sites of the cleft (sites A-C), but not reach sites D and E, where the enzyme cuts the glycosidic bond. So, the competitive inhibitor will stick in the cleft, not allowing the substrate to bind to the enzyme complex.<ref>http://mcdb-webarchive.mcdb.ucsb.edu/sears/biochemistry/tw-enz/lysozyme/HEWL/lysozyme-overview.htm</ref> Several known inhibitors of lysozyme are SDS, N-acetyl-D-glucosamine, and various alcohols and oxidizing agents.<ref>http://www.worthington-biochem.com/ly/default.html</ref> | |||
