Lysozymes (EC. 188.8.131.52) are widely recognized for their contribution to the antibacterial defense in many animals and their use as a preservative in foods and pharmaceuticals.  The key characteristic for all lysozymes is their ability to hydrolyze the ß-(1-4)-glycosidic bond between the alternating residues of peptidoglycan, a unique bacterial cell wall polymer. There are many approaches to study the lysozyme activity such as using chitooligosaccharides, but these approaches often require study for overall kinetic rates to later dissect into individual rates. Ogata, et. al. were able to create a novel analytical procedure for studying lysozyme activity undergoing a single cleavage reaction, which simplifies the kinetic measurements.
The research group was able to synthesize ß-D-galactosyl-
Ogata, et. al. used quantitative HPLC-UV to aid this development of this novel analytical procedure. They used HPLC-UV to study the enzymatic-transglycosylation reaction for the synthesis of Gal(
