Giuseppe Dionisio et al.
Molecules (Basel, Switzerland), 24(13) (2019-07-10)
Xenobiotic detoxification in plant as well as in animals has mostly been studied in relationship to the deactivation of the toxic residues of the compound that, surely for azoxystrobin, is represented by its β-methoxyacrylate portion. In maize roots treated for
Timo Glatter et al.
Molecular systems biology, 5, 237-237 (2009-01-22)
Protein complexes represent major functional units for the execution of biological processes. Systematic affinity purification coupled with mass spectrometry (AP-MS) yielded a wealth of information on the compendium of protein complexes expressed in Saccharomyces cerevisiae. However, global AP-MS analysis of
Ivo M B Francischetti et al.
Journal of proteome research, 9(8), 3820-3831 (2010-05-06)
The evolution of insects to a blood diet leads to the development of a saliva that antagonizes their hosts' hemostasis and inflammation. Hemostasis and inflammation are redundant processes, and thus a complex salivary potion composed of dozens or near 100
Chiara Nitride et al.
Analytical and bioanalytical chemistry, 411(16), 3463-3475 (2019-05-30)
The unintentional presence of even trace amounts of certain foods constitutes a major hazard for those who suffer from food allergies. For many food industries, product and raw ingredient surveillance forms part of their risk assessment procedures. This may require
S B Bilezikian et al.
The Journal of clinical investigation, 56(2), 438-445 (1975-08-01)
Thrombin converts fibrinogen to fibrin monomer by cleaving fibrinopeptides A and B (FPA and FPB) from the amino terminal ends of the A (alpha) and B (beta) chains. A radioimmunoassay capable of measuring the A peptide in human blood as
Gerold Schmitt-Ulms et al.
PloS one, 4(9), e7208-e7208 (2009-09-29)
In the more than twenty years since its discovery, both the phylogenetic origin and cellular function of the prion protein (PrP) have remained enigmatic. Insights into a possible function of PrP may be obtained through the characterization of its molecular
Helena Firczuk et al.
The FEBS journal, 287(5), 925-940 (2019-09-15)
Control of complex intracellular pathways such as protein synthesis is critical to organism survival, but is poorly understood. Translation of a reading frame in eukaryotic mRNA is preceded by a scanning process in which a subset of translation factors helps
Anthony W Purcell et al.
Nature protocols, 14(6), 1687-1707 (2019-05-17)
Peptide antigens bound to molecules encoded by the major histocompatibility complex (MHC) and presented on the cell surface form the targets of T lymphocytes. This critical arm of the adaptive immune system facilitates the eradication of pathogen-infected and cancerous cells
D Andrew James et al.
Journal of pharmaceutical sciences, 107(12), 3022-3031 (2018-09-04)
HSV529 is a replication defective human herpes simplex virus (HSV)-2 viral vaccine candidate in clinical development. An engineered cell line is required to support production of HSV529 by transgenic expression of the HSV-1 transcription factors UL5 (HELI) and UL29 (DNBI).
Johnson Agniswamy et al.
Acta crystallographica. Section D, Biological crystallography, 64(Pt 4), 354-367 (2008-04-09)
Heavy-atom derivatization is routinely used in protein structure determination and is thus of critical importance in structural biology. In order to replace the current trial-and-error heavy-atom derivative screening with a knowledge-based rational derivative-selection method, the reactivity of more than 40
Kélen Fabíola Arroteia et al.
PloS one, 9(8), e103566-e103566 (2014-08-02)
The epididymis has an important role in the maturation of sperm for fertilization, but little is known about the epididymal molecules involved in sperm modifications during this process. We have previously described the expression pattern for an antigen in epididymal
Chao Wang et al.
The Journal of biological chemistry, 285(35), 26788-26797 (2010-06-03)
Protein disulfide isomerase (PDI), which consists of multiple domains arranged as abb'xa'c, is a key enzyme responsible for oxidative folding in the endoplasmic reticulum. In this work we focus on the conformational plasticity of this enzyme. Proteolysis of native human
Andrew T Crombie et al.
Nature, 510(7503), 148-151 (2014-04-30)
The climate-active gas methane is generated both by biological processes and by thermogenic decomposition of fossil organic material, which forms methane and short-chain alkanes, principally ethane, propane and butane. In addition to natural sources, environments are exposed to anthropogenic inputs
Lawrence M Schopfer et al.
Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 878(17-18), 1297-1311 (2009-09-19)
We have identified organophosphorus agent (OP)-tyrosine adducts on 12 different proteins labeled with six different OP. Labeling was achieved by treating pure proteins with up to 40-fold molar excess of OP at pH 8-8.6. OP-treated proteins were digested with trypsin
Nicholas M Frame et al.
Journal of molecular biology, 432(7), 1978-1995 (2020-02-10)
Serum amyloid A (SAA) is a plasma protein that transports lipids during inflammation. To explore SAA solution conformations and lipid-binding mechanism, we used hydrogen-deuterium exchange mass spectrometry, lipoprotein reconstitution, amino acid sequence analysis, and molecular dynamics simulations. Solution conformations of
Kristin E Burns et al.
The Journal of biological chemistry, 284(5), 3069-3075 (2008-11-26)
The striking identification of an apparent proteasome core in Mycobacteria and allied actinomycetes suggested that additional elements of this otherwise strictly eukaryotic system for regulated protein degradation might be conserved. The genes encoding this prokaryotic proteasome are clustered in an
R M Senior et al.
The Journal of clinical investigation, 77(3), 1014-1019 (1986-03-01)
Fibrin formation and turnover are intimately associated with inflammation and wound healing. To explore whether fibrin(ogen)-derived peptides exert direct effects upon cells involved in inflammation and tissue repair we examined the capacity of human fibrinopeptide B (hFpB), a thrombin-derived proteolytic
Lukas N Mueller et al.
Proteomics, 7(19), 3470-3480 (2007-08-30)
Label-free quantification of high mass resolution LC-MS data has emerged as a promising technology for proteome analysis. Computational methods are required for the accurate extraction of peptide signals from LC-MS data and the tracking of these features across the measurements
