The isolation of a disaccharide, N-acetyl-β-D-glucosaminyl-(1 → 4) N-acetylmuramic acid (NAG-NAM) and a corresponding tetrasaccharide, from lysozyme digests of Micrococcus lysodeikticus cell walls, is described. These compounds have been used for the study of the enzymic activity of lysozyme. Digestion of the tetrasaccharide into disaccharide has been followed by (a) paper chromatography, (b) colorimetry, using the Morgan-Elson reaction, and (c) polarimetry. Lysozyme was found to catalyse…

Inhibition of Lysozyme by N-Acyl-D-glucosamine Derivatives
The detailed mechanisms of the enzyme function and specificity are not completely established, but it is known to hydrolyse the β(1→4) glycosidic linkages in the glycoaminopeptide component of the cell walls of Micrococcus lysodeikticus and those of chitin.
Low-molecular-weight substrate for the lysozyme of T4 bacteriophage.
The substrate may be used for the specific identification of murein N-acetylmuramoylhydrolases of the T4 lysozyme type, as well as for any quantitative measurement of the enzymatic reaction.
Comparative Studies of the Active Site Region of Lysozymes from Eleven Different Sources
The lysozymes of group I are irreversibly inactivated by the epoxypropyl β-glycosides and exhibit similar fluorescence spectra which shift to the blue upon the addition of tri-(N-acetyl-D-glucosamine), which suggest that they can be classified into two groups.
Specific and Irreversible Inhibition of Lysozyme by 2′,3′-Epoxypropyl β-Glycosides of N-Acetyl-D-glucosamine Oligomers
An attempt to design specific inhibitors of lysozyme, using the affinity labelling principle, is described, because the side chains of amino-acid residues Glu 35 and Asp 52 have been proposed as the catalytically active groups in ly sozyme.
Oligosaccharides containing Glucose as Substrates for Hen's Egg White Lysozyme
The results obtained provide information on the specificity requirements of subsites C and D in the active site of lysozyme and allow further insight to be gained into the role of strain as a major factor involved in lyso enzyme catalysis.
The binding of glycoconjugates to human-milk D-galactosyltransferase.
It appears that alpha-lactalbumin can only modify human A protein for monosaccharide acceptors.
Microcalorimetric study of binding by lysozyme of N-acetyl glucosamine oligomers.
It is concluded that the mode of binding of the monomer and dimer is different from that of the trimer, tetramer, pentamer and hexamer, and that the monomers and dimers comprise one group while the trimers and tetramer comprise the second group deriving additional stability principally from site A, with the hexamer falling between them.
Effect of N-acyl substitution at glucosamine residues on lysozyme-catalyzed hydrolysis of cell-wall peptidoglycan and its oligosaccharides.
The effect of N-substitution with various acyl groups at glucosamine residues on lysozyme-catalyzed hydrolysis of cell wall peptidoglycan and its oligosaccharides was studied and the predominant importance of the alkyl moieties of the N-acyl substituents on the glucosamines located in subsite C in the enzyme-substrate complexes was accounted for.
