Oxidation of proteins and peptides is a common phenomenon, and can be employed as a labeling technique for mass-spectrometry-based proteomics. Nonspecific oxidative labeling methods can modify almost any amino acid residue in a protein or only surface-exposed regions. Specific agents may label reactive functional groups in amino acids, primarily cysteine, methionine, tyrosine, and tryptophan. N...

let $g=(v‎, ‎e)$ be a graph with $p$ vertices and $q$ edges‎. ‎an emph{acyclic‎ ‎graphoidal cover} of $g$ is a collection $psi$ of paths in $g$‎ ‎which are internally-disjoint and cover each edge of the graph‎ ‎exactly once‎. ‎let $f‎: ‎vrightarrow {1‎, ‎2‎, ‎ldots‎, ‎p}$ be a bijective‎ ‎labeling of the vertices of $g$‎. ‎let $uparrow!g_f$ be the‎ ‎directed graph obtained by orienting the...

background: gallium-66 (t1/2= 9.49 h) is an interesting radionuclide that has potential for positron emission tomography (pet) imaging of biological processes in intermediate to slow target tissue uptake. oxine has been labeled with this radioisotope in the form of [66ga]gallium chloride for its possible diagnostic properties. materials and methods: 66ga was produced in the 30 mev cyclotron (cy...

Genetic code expansion and bioorthogonal labeling provide for the first time a way for direct, site-specific labeling of proteins with fluorescent-dyes in live cells. Although the small size and superb photophysical parameters of fluorescent-dyes offer unique advantages for high-resolution microscopy, this approach has yet to be embraced as a tool in live cell imaging. Here we evaluated the fea...

Bacterial resistance to antibiotics poses a great clinical challenge in fighting serious infectious diseases due to complicated resistant mechanisms and time-consuming testing methods. Chemical reaction-directed covalent labeling of resistance-associated bacterial proteins in the context of a complicated environment offers great opportunity for the in-depth understanding of the biological basis...

During greening of fat-storing cotyledons, the functional properties of the microbody population changes from that of glyoxysomes to that of leaf peroxisomes. The amount of microbody protein per cell is assumed to be substantially reduced [ 1,2,3] . Little is known about the mechansim of this change of microbody function. Recently, data obtained from labeling of microbody membranes with Cl4 and...
