Precursor of Egg White Lysozyme
Lysozyme mRNA was translated in a reticulocyte lysate with mixtures of radioactive amino acids. The in vitro product isolated by immunoprecipitation was shown by gel electrophoresis, peptide mapping, and sequence analysis to be larger than lysozyme synthesized in uiuo. An NH,-terminal extension was completely sequenced by automated Edman degradation; the phenylthiohydantoins from each cycle wer...
متن کاملHen 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 کاملSelection and characterization of DNA aptamers for egg white lysozyme.
We have selected aptamers binding to lysozyme from a DNA library using capillary electrophoresis-systematic evolution of ligands by exponential enrichment. During the selection process the dissociation constant of the ssDNA pool decreased from the micromolar to the low nanomolar range within five rounds of selection. The final aptamer had a dissociation constant of 2.8 +/- 0.3 nM, 6.1 +/- 0.5 n...
متن کاملRadiation-produced aggregation and inactivation in egg white lysozyme.
Chromatographically homogeneous egg white lysozyme has been subjected under reduced pressure to 0.67-m.e.v. y-rays. At 37% destruction of enzymic activity, three inactive aggregates and one partially active fraction have been isolated by salt precipitation and chromatographic procedures. The aggregates, upon reduction with 2-mercaptoethanol and reaction with iodoacetic acid, give derivatives wi...
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...
