in recent years, several oconjugation protocols have been developed to improve the functional properties of the enzyme lysozyme. in this study, the optimum conditions of lysozyme – oxidized inulin conjugation and functional properties of the modified lysozyme were investigated. initially, inulin (mw about 25 kda) was oxidized by periodate to provide the reactive carbonyl groups  to attach to am...

protein aggregation is a serious problem for both biotechnology and cell biology. diseases such as prion misfolding, alzheimer’s, and other amyloidosis are phenomena for which protein aggregation in our living cells is of considerable relevance. human lysozyme has been shown to form amyloid fibrils in individuals suffering from nonneuropathic systemic amyloidosis, all of which have point mutati...

lysozyme is considered as part of the innate immune system. it has stimulated considerable interest as a natural food preservative. lysozyme has been shown to be effective in preserving a variety of foods such as fresh fruits and vegetables, meats, seafood and wine, for which many japanese patents have been granted. the relatively high thermal stability of lysozyme also makes it attractive for ...

lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, gly...

effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...

in order to increase the water content and the oxygen permeability of hydrogels used in themanufacture of contact lenses, the polar monomer silicon hydrogel contact lenses (shcl), and 2-hydroxyethyl methacrylate (hema) were copolymerized with the hydrogels. due to the presence ofpolar monomers in the conventional contact lenses, the major component of the human tear,lysozyme is extensively adso...

Lysozyme is one of the most abundant antimicrobial proteins in the airspaces of the lung. Mice express two lysozyme genes, lysozyme M and P, but only the M enzyme is detected in abundance in lung tissues. Disruption of the lysozyme M locus significantly increased bacterial burden and mortality following intratracheal infection with a Gram-negative bacterium. Unexpectedly, significant lysozyme e...

background and aims. lysozyme and lactoferrin are salivary proteins which play an important role in innate defense mechanisms against bacteria. this study investigated the association of salivary lysozyme and lactoferrin concentrations with early childhood caries (ecc). materials and methods. this study was carried out on 42 healthy children (age range, 36 to 71 months), of whom 21 were caries ...

lysozyme is a bactericidal enzyme whose structure and functions change in diabetes. chemical chaperones are small molecules including polyamines (e.g. spermine), amino acids (e.g. l-lysine) and polyols (e.g. glycerol). they can improve protein conformation in several stressful conditions such as glycation. in this study, the authors aimed to observe the effect of l-lysine as a chemical chaperon...
