Lower map densities for the link between C374 and pyrene and around G48 and higher B-factors are evidence of greater mobility in Mg-ADP-pyrenyl-actin filaments. Chemical and post-translational modifications of C374: actin C374 can be post-translationally modified by oxidation, glutathionylation,...
a, The mechanism of ADP-ribosylation for Arg. Initially, the N-glycosidic bond between the ribose and nicotinamide is destabilized by a Glu residue of an ART. This leads to the formation of an oxocarbenium ion of ADPr, with nicotinamide as the leaving group. This electrophilic ion is atta...
Analysis of the sample extracts involved the utilization of ultra-high pressure liquid chromatography (UHPLC), coupled with ion mobility separation (IMS), and high-resolution mass spectrometry (HRMS). Arginine, urocanic acid, erythro-sphingosine (d171), sphingosine (d181), and sphinganine were ...
While lipoylation increased the electrophoretic mobility (Ali et al., 1990), MARylation led to a distinct retention (Figure 4I). We estimate that under our assay conditions, ∼50% of the GcvH-L protein is lipoylated and 5% of the initial substrate becomes ADP-ribosylated. Importantly, M...
Nuclear Extraction and Electrophoretic Mobility Shift Assays (EMSAs) Nuclear extracts of Raji cells were essentially prepared as described earlier [13]. For the EMSA reaction, a double-stranded oligonucleotide coding for bp -400 to -357 of the S100A9 promoter was used. The sense oligonucleotide CAG...
(C) Electrophoretic mobility shift assays (EMSAs) of full-length NR4A2 proteins showing sequence-specific DNA binding to NBRE or mutNBRE (mutated) oligo. (D) Reporter gene assays with NBRE- and NuRE-based luciferase reporters. RLU, relative luciferase activity. Graph represents mean RLU value...
If a substrate is ADP-ribosylated by HopU1, the substrate's molecular mass would be expected to increase by 541 Da increments (the molecular mass of ADP-ribose) as indicated by a shift in mobility. In another aspect, the HopU1 substrates are substrates of HopU1 identified in vivo. In ...
DPI-ELISA is a new technique to detect the interaction between DNA and protein, through immunoreaction. Compared with the traditional electrophoretic mobility shift assay, DPI-ELISA has more advantages because it does not rely on radioactive detection. In addition, DPI-ELISA displays a 10-fold incr...
