Photosensitized Formation of Soluble Bionanoparticles of Lysozyme
(John Wiley & Sons Ltd, 2021-12)
Photosensitized crosslinking of hen egg-white lysozyme (LZ) in buffer solutions was obtained by blue-LED excitation of ruthenium (II) tris-bipyridyl dication (Ru(bpy)32+) in a molar excess of persulfate anion (S2O82−), ...
A novel synthetic approach to tyrosine dimers based on pterin photosensitization
(Elsevier, 2017-12)
Oxidative damage to proteins leads to a variety of modifications that are markers of pathogenesis. One of the most important modifications is the dityrosine (Tyr2) cross-link, resulting from an oxidative covalent bond ...
Structure and post-translational modifications of the web silk protein spidroin-1 from Nephila spiders
(Elsevier B.V., 2014-06-13)
Spidroin-1 is one of the major ampullate silk proteins produced by spiders for use in the construction of the frame and radii of orb webs, and as a dragline to escape from predators. Only partial sequences of spidroin-1 ...
The peroxyl radical-induced oxidation of Escherichia coli FtsZ and its single tryptophan mutant (Y222W) modifies specific side-chains, generates protein cross-links and affects biological function
(Elsevier Inc., 2017)
© 2017 Elsevier Inc. FtsZ (filamenting temperature-sensitive mutant Z) is a key protein in bacteria cell division. The wild-type Escherichia coli FtsZ sequence (FtsZwt) contains three tyrosine (Tyr, Y) and sixteen methionine ...
Free radicals derived from γ-radiolysis of water and AAPH thermolysis mediate oxidative crosslinking of eGFP involving Tyr-Tyr and Tyr-Cys bonds: the fluorescence of the protein is conserved only towards peroxyl radicals
(Elsevier, 2020)
The enhanced green fluorescent protein (eGFP) is one of the most employed variants of fluorescent proteins.
Nonetheless little is known about the oxidative modifications that this protein can undergo in the cellular ...
