3-Nitrotyrosine and related derivatives in proteins: precursors, radical intermediates and impact in function
(Journal of the Serbian Chemical Society, 2020-02)
Oxidative post-translational modification of proteins by molecular oxygen (O2)- and nitric oxide (•NO)-derived reactive species is a usual process that occurs in mammalian tissues under both physiological and pathological ...
Solvent mimicry with methylene carbene to probe protein topography
(American Chemical Society, 2015-09)
The solvent accessible surface area (SASA) of the polypeptide chain plays a key role in protein folding, conformational change, and interaction. This fundamental biophysical parameter is elusive in experimental measurement. ...
An antiviral disulfide compound blocks interaction between arenavirus Z protein and cellular promyelocytic leukemia protein
(Academic Press Inc Elsevier Science, 2010)
Sequence analysis, expression, and paratope characterization of a single-chain Fv fragment for the eukaryote ribosomal P proteins
(Elsevier, 2003-03)
The variable genes of monoclonal antibody (mAb) B10, specific for the C-terminal region of the eukaryotic ribosomal P protein, have been cloned as a single-chain Fv fragment (scFv) and expressed in Escherichia coli. The ...
Albumin-mediated deposition of bone-like apatite onto nano-sized surfaces: Effect of surface reactivity and interfacial hydration
(Academic Press Inc Elsevier Science, 2017-05)
The bioactivity of an implant is displayed on its ability to induce heterogeneous nucleation of biogenic apatite onto its surface upon immersion in body fluids; forming, through this layer, a stable bond with the host ...
On the generation and quenching of reactive-oxygen-species by aqueous vitamin B2 and serotonin under visible-light irradiation
(Elsevier Science Sa, 2012-04)
It is well known that endogenous daylight-absorbing compounds produce the sensitized photodegradation of biologically relevant substrates. In this context the photostability of a mixture of the indole neurotransmitter ...
The reduced myofilament responsiveness to calcium contributes to the negative force-frequency relationship in rat cardiomyocytes: role of reactive oxygen species and p-38 map kinase
(Springer, 2017-12)
The force-frequency relationship (FFR) is an important intrinsic regulatory mechanism of cardiac contractility. However, a decrease (negative FFR) or no effect (flat FFR) on contractile force in response to an elevation ...
Baseline defense system of commercial king crabs Lithodes santolla from the Beagle Channel
(Elsevier, 2014-11)
Environmental and physiological variations influence the steady-state concentration of free oxygen radicals in cells. Because of the seasonal life cycle of Lithodes santolla in the Beagle Channel, a baseline study of the ...
Current status and perspectives on the role of polyamines in plant immunity
(Wiley Blackwell Publishing, Inc, 2021-01)
Polyamines are low molecular weight amines, with versatile and essential functions during the lifespan of prokaryotes and eukaryotes. Modulation of polyamine metabolism under biotic stress has attracted a great deal of ...
