Structure of macrodomain walls in polytwinned magnets

open access: yesJournal of Applied Physics, 2002
We propose a microscopic approach to the studies of magnetic configurations in hard magnets which may be conveniently used for nanoscale systems; the microstructure of the magnet is easily and naturally included in the calculations. This approach is applied to find the structure of macrodomain walls in polytwinned magnets of the CoPt family ...

Recognition of Mono-ADP-Ribosylated ARTD10 Substrates by ARTD8 Macrodomains [PDF]

open access: yesStructure, 2013
ADP-ribosyltransferases (ARTs) catalyze the transfer of ADP-ribose from NAD(+) onto substrates. Some ARTs generate in an iterative process ADP-ribose polymers that serve as adaptors for distinct protein domains. Other ARTs, exemplified by ARTD10, function as mono-ADP-ribosyltransferases, but it has been unclear whether this modification occurs in cells

Single-nucleotide resolution detection of Topo IV cleavage activity in the Escherichia coli genome with Topo-Seq

open access: yesFrontiers in Microbiology, 2023
Topoisomerase IV (Topo IV) is the main decatenation enzyme in Escherichia coli; it removes catenation links that are formed during DNA replication. Topo IV binding and cleavage sites were previously identified in the E.

Computational Investigations of Traditional Chinese Medicinal Compounds against the Omicron Variant of SARS-CoV-2 to Rescue the Host Immune System

open access: yesPharmaceuticals, 2022
Macrodomain-I of the NSP3 (non-structural protein 3) is responsible for immune response hijacking in the SARS-CoV-2 infection known as COVID-19. In the omicron variant (B.1.1.529), this domain harbors a new mutation, V1069I, which may increase the ...

Dielectric behavior and phase transition in [111]-oriented PIN–PMN–PT single crystals under dc bias [PDF]

open access: yesJournal of Advanced Dielectrics, 2014
Temperature and electric field dependences of the dielectric behavior and phase transition for [111]-oriented 0.23PIN–0.52PMN–0.25PT (PIN-PMN–0.25PT) and 0.24PIN–0.43PMN–0.33PT (PIN–PMN–0.33PT) single crystals were investigated over a temperature range ...

A family of macrodomain proteins reverses cellular mono-ADP-ribosylation [PDF]

open access: yesNature Structural & Molecular Biology, 2013
ADP-ribosylation is a reversible post-translational modification with wide-ranging biological functions in all kingdoms of life. A variety of enzymes use NAD(+) to transfer either single or multiple ADP-ribose (ADPr) moieties onto distinct amino acid substrates, often in response to DNA damage or other stresses.

Serine ADP-ribosylation reversal by the hydrolase ARH3

open access: yeseLife, 2017
ADP-ribosylation (ADPr) is a posttranslational modification (PTM) of proteins that controls many cellular processes, including DNA repair, transcription, chromatin regulation and mitosis. A number of proteins catalyse the transfer and hydrolysis of ADPr,

Proximal ADP-ribose Hydrolysis in Trypanosomatids is Catalyzed by a Macrodomain

open access: yesScientific Reports, 2016
AbstractADP-ribosylation is a ubiquitous protein modification utilized by both prokaryotes and eukaryotes for several cellular functions, such as DNA repair, proliferation and cell signaling. Higher eukaryotes, such as humans, utilize various enzymes to reverse the modification and to regulate ADP-ribose dependent signaling.

Characterization of Brucella abortus lipopolysaccharide macrodomains as mega rafts

open access: yesCellular Microbiology, 2006
The lipopolysaccharides (LPS) of intracellular Proteobacteria such as Brucella, Chlamydia, Legionella and Rickettsia, have properties distinct from enterobacterial LPSs. These properties include deficient LPS induction of host cell activation, low endotoxicity and resistance to macrophage degradation.
