Arsenite binds to the RING finger domains of RNF20-RNF40 histone E3 ubiquitin ligase and inhibits DNA double-strand break repair. [PDF]

open access: yes, 2014
Arsenic is a widespread environmental contaminant. However, the exact molecular mechanisms underlying the carcinogenic effects of arsenic remain incompletely understood.

Hydrophobicity causes anomalous migration of cystine/glutamate antiporter SLC7A11 in SDS‐PAGE with low acrylamide concentration

open access: yesFEBS Open Bio, EarlyView.
SLC7A11 frequently migrates faster in SDS‐PAGE. The present study found that the high hydrophobicity of SLC7A11 causes its anomalous migration in SDS‐PAGE with a low concentration of acrylamide gel. Replacing isoleucine with asparagine reduced hydrophobicity and restored its normal migration at 55 kDa, revealing the role of hydrophobicity and gel ...

Differential recruitment of DNA Ligase I and III to DNA repair sites [PDF]

open access: yes, 2006
DNA ligation is an essential step in DNA replication, repair and recombination. Mammalian cells contain three DNA Ligases that are not interchangeable although they use the same catalytic reaction mechanism.

Enhanced discovery of bacterial laccase‐like multicopper oxidase through computer simulation and metagenomic analysis of industrial wastewater

open access: yesFEBS Open Bio, EarlyView.
We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.

Biosynthesis of mammalian DNA ligase.

open access: yesJournal of Biological Chemistry, 1985
A monospecific antibody against calf thymus DNA ligase composed of a single polypeptide with Mr = 130,000 cross-reacts with rodent and calf thymus DNA ligases. The antibody precipitates a single Mr = 200,000 polypeptide from detergent lysates of [3H] leucine-labeled mouse Ehrlich tumor cells and calf thymocytes. Pulse-chase experiments show that the Mr

FEM1B enhances TRAIL‐induced apoptosis in T lymphocytes and monocytes

open access: yesFEBS Open Bio, EarlyView.
FEM1B facilitates TRAIL‐induced apoptosis through distinct mechanisms in T lymphocytes and monocytes. In T lymphocytes, FEM1B engages with TRAF2, leading to a reduction in TRAF2 expression, which subsequently lessens TRAF2's inhibitory influence on caspase‐8.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

CRL Ubiquitin Ligases and DNA Damage Response [PDF]

open access: yes, 2012
Cullin/RING ubiquitin ligases (CRL) comprise the largest subfamily of ubiquitin ligases. CRLs are involved in cell cycle regulation, DNA replication, DNA damage response (DDR), development, immune response, transcriptional regulation, circadian rhythm ...

DNA unwinding and inhibition of T4 DNA ligase by anthracyclines

open access: yesNucleic Acids Research, 1988
The ability to alter DNA tertiary structure of ten anthracycline derivatives whose antitumor potency is known was studied by an assay that makes use of nicked circular DNA and bacteriophage T4 DNA ligase. This assay allows the detection of tertiary structure alterations caused by DNA binding of both intercalating and non-intercalating drugs.

Structural and mechanistic conservation in DNA ligases [PDF]

open access: yesNucleic Acids Research, 2000
DNA ligases are enzymes required for the repair, replication and recombination of DNA. DNA ligases catalyse the formation of phosphodiester bonds at single-strand breaks in double-stranded DNA. Despite their occurrence in all organisms, DNA ligases show a wide diversity of amino acid sequences, molecular sizes and properties.
