New classes of E3 ligases illuminated by chemical probes [PDF]

open access: yes, 2022
Specificity in the ubiquitin system depends on E3 ligases, largely belonging to a handful of families discovered more than a decade ago. However, the last two years brought a quantum leap in the identification and/or mechanistic characterization of ...

Archaeal Genes Code for GGDEF Domain Proteins With Diguanylate Cyclase Activity

open access: yesMolecular Microbiology, Volume 126, Issue 5, Page 576-595, November 2026.
A biofilm‐like mode of growth is hypothesized to be required for the emergence of cellular life. Occurrence of common biofilm gene products in current Bacteria and Archaea is an indication for their previous presence in the last universal common ancestor LUCA and perhaps even in the first universal common ancestor FUCA.

Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

open access: yesAdvanced Materials, Volume 38, Issue 56, 8 October 2026.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Repair of Alkylated Bacteriophage T4 Deoxyribonucleic Acid by a Mechanism Involving Polynucleotide Ligase [PDF]

open access: yesJournal of Virology, 1971
Methyl methanesulfate-induced lesions in bacteriophage T4 are repaired primarily by a mechanism involving polynucleotide ligase. Apparently, other recombinational and ultraviolet repair functions aren't involved.

Endogenous Protein Tagging in Postmitotic Neurons via Lentiviral and Adeno‐associated Virus Delivery

open access: yesCurrent Protocols, Volume 6, Issue 10, October 2026.
Abstract This protocol describes a method for endogenous protein tagging in postmitotic primary neurons using homology‐independent targeted integration (HITI), a CRISPR/Cas9‐based approach that exploits non‐homologous end joining (NHEJ). Unlike homology‐directed repair (HDR), HITI does not require cell division, making it uniquely suited for ...

PEBP1 Regulates Ferroptosis in Acute Glaucoma: Targeted Therapy Using Engineered Exosomes

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
General schematic diagram of Spatial and Single‐Cell Transcriptomics Identifies PEBP1 as a Ferroptosis Mediator in Glaucoma: Targeted Intervention by Engineered Stem Cell Exosomes. ABSTRACT Glaucoma is the leading cause of irreversible blindness worldwide, primarily driven by the progressive loss of retinal ganglion cells (RGCs) under pathological high

The Significance of cGAS‐STING Signaling in Response to Oncogenic Viruses

open access: yesCell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT The cyclic GMP‐AMP synthase (cGAS)‐stimulator of interferon genes (STING) signaling pathway, as a key DNA sensor, plays a significant role in the regulation of innate immune responses. This pathway can be activated by sensing abnormal DNA, and is of great significance for resisting the invasion of pathogenic microorganisms and maintaining ...

Bacterial DNA ligases

open access: yes, 2001
DNA ligases join breaks in the phosphodiester backbone of DNA molecules and are used in many essential reactions within the cell. All DNA ligases follow the same reaction mechanism, but they may use either ATP or NAD+ as a cofactor.

Technologies for engineering repetitive DNA

open access: yesQuantitative Biology, Volume 14, Issue 3, September 2026.
Abstract Repetitive DNA, a fundamental architectural element of genomes, is widespread across organisms and comprises about 54% of the human genome. With advances in long‐read sequencing and bioinformatics approaches, highly repetitive sequences can now be characterized in depth.
