Hen Egg - white Lysozyme Crystals
Proton tautomerism is a general phenomenon in organic molecules and plays a vital role in many fields of chemistry and biochemistry. The tautomerism of salicylideneanilines [eq(1)] has attracted a considerable attention because it is closely related to thermoand photochromism. Salicylideneanilines greatly favor the enol form over the cis-keto form in the gas phase. We demonstrate here that the ...
متن کاملDigestibility and Enzymatic Activity in Vitro of Hen Egg White Lysozyme
Objective: The aim of this study was to evaluate the protein digestibility and analyze the residual enzymatic activity of lysozyme. Methods: Protein digestibility was evaluated hydrolyzing the protein with pepsin at pH 1.2, 2.0, and 3.2 during 60, 90, and 120 minutes of incubation. These hydrolysates were analyzed with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and reversed-phase...
متن کاملStudy the Interaction of Ni Complex of Tetradentate Schiff Base Ligand with HEN Egg White Lysozyme
AbstractInteraction of Ni complex(Salen= N, N´-ethylene bis(salicylideneimine)) with hen egg-white lysozyme (HEWL) was studied by absorption spectroscopy, competitive binding study and thermal denaturation study. The protein binding affinity of Ni complex was found to be (3.0×103M−1). The binding plot obtained from the absorption titration data gives a binding constant of 2.4 (± 0.3)×103 M...
متن کاملCharacterization of the unfolding pathway of hen egg white lysozyme.
After the recent discovery of a ribonuclease A unfolding intermediate [Kiefhaber, T., et al. (1995) Nature 375, 513-515], we investigated the unfolding pathway of hen egg white lysozyme. At pH* 4.00 with D2O at 10 degrees C and 6 M guanidinium chloride, unfolding shows a single, slow kinetic phase, with a relaxation time of 3300 s when monitored by circular dichroism (CD). Exchange of the trypt...
متن کاملthermal aggregation of hen egg white lysozyme: effect of polyamines
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...
