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.

Long range chromosome organization in Escherichia coli: The position of the replication origin defines the non-structured regions and the Right and Left macrodomains. [PDF]

open access: yesPLoS Genetics, 2017
The Escherichia coli chromosome is organized into four macrodomains (Ori, Ter, Right and Left) and two non-structured regions. This organization influences the segregation of sister chromatids, the mobility of chromosomal DNA, and the cellular ...

SARS‐CoV‐2 Variants and Immune Evasion: Mapping the Future of Vaccine Design

open access: yesReviews in Medical Virology, Volume 36, Issue 3, May 2026.
ABSTRACT The evolutionary trajectory of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2) has progressed through several distinct phases since its zoonotic emergence, transitioning from initial human adaptation to an era of rapid antigenic drift and complex immune evasion. As of early 2026, the global landscape is dominated by highly evolved

Superconductivity in Sr2RuO4-Sr3Ru2O7 eutectic crystals

open access: yes, 2007
Superconducting behavior has been observed in the Sr2RuO4-Sr3Ru2O7 eutectic system as grown by the flux-feeding floating zone technique. A supercurrent flows across a single interface between Sr2RuO4 and Sr3Ru2O7 areas at distances that are far beyond ...

Multiorgan Molecular Landscape of Severe COVID‐19 Revealed by Consensus Gene Signatures and RAB8B Targeting

open access: yesJournal of Medical Virology, Volume 98, Issue 4, April 2026.
ABSTRACT Severe COVID‐19 involves hyperinflammation and multiorgan pathology, but consistent gene signatures remain elusive. We aimed to identify consensus transcriptomic signatures and molecular mechanisms in severe COVID‐19. We performed an integrative analysis of 39 studies spanning 11 tissue types, 1551 bulk RNA‐seq samples, and over 2 million ...

A macrodomain-linked immunosorbent assay (MLISA) for mono-ADP-ribosyltransferases [PDF]

open access: yesAnalytical Biochemistry, 2018
ADP-ribosyltransferases (ARTs) catalyze reversible additions of mono- and poly-ADP-ribose onto diverse types of proteins by using nicotinamide adenine dinucleotide (NAD+) as a cosubstrate. In the human ART superfamily, 14 out of 20 members are shown to catalyze endogenous protein mono-ADP-ribosylation and play important roles in regulating various ...

Streptomyces coelicolor macrodomain hydrolase SCO6735 cleaves thymidine-linked ADP-ribosylation of DNA

open access: yesComputational and Structural Biotechnology Journal, 2022
ADP-ribosylation is an ancient, highly conserved, and reversible covalent modification critical for a variety of endogenous processes in both prokaryotes and eukaryotes.

Design, synthesis and evaluation of inhibitors of the SARS-CoV-2 nsp3 macrodomain

open access: yesbioRxiv, 2022
A series of amino acid based 7H-pyrrolo[2,3-d]pyrimidines were designed and synthesized to discern the structure activity relationships against the SARS-CoV-2 nsp3 macrodomain (Mac1), an ADP-ribosylhydrolase that is critical for coronavirus replication ...

Recent advances in noncanonical inhibition mechanisms of anti‐CRISPR proteins

open access: yesmLife, Volume 5, Issue 2, Page 133-147, April 2026.
Abstract The CRISPR‐Cas system constitutes an adaptive immune mechanism in prokaryotes that defends against mobile genetic elements. Within the perpetual co‐evolutionary arms race between bacteria and their viral predators, bacteriophages encode anti‐CRISPR (Acr) proteins that use sophisticated molecular strategies to sabotage CRISPR‐Cas function ...
