T4 DNA ligase synthesizes dinucleoside polyphosphates [PDF]
T4 DNA ligase (EC 6.5.1.1), one of the most widely used enzymes in genetic engineering, transfers AMP from the E-AMP complex to tripolyphosphate, ADP, ATP, GTP or dATP producing p4A, Ap3A, Ap4A, Ap4G and Ap4dA, respectively.

Analysis of the distribution and evolution of the
SummaryPrior to the discovery of a minimal ATP‐dependent DNA ligase in Haemophilus influenzae, bacteria were thought to only possess a NAD‐dependent ligase, which was involved in sealing of Okazaki fragments. We now know that a diverse range of bacterial species possess up to six of these accessory bacterial ATP‐dependent DNA ligases (b‐ADLs), which ...

Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

ATP-dependent DNA supercoiling assay.
Supercoiling activities of DNA gyrases composed of WT-GyrA, Gly89Cys-GyrA, Ala91Val-GyrA or Asp95Gly-GyrA and WT-GyrB were confirmed. Relaxed pBR322 DNA was incubated with GyrA, GyrB, or both, of the subunits in the presence or absence of ATP.

Analysis of the DNA damage response in living cells [PDF]
DNA lesions arising from environmental and endogenous sources induce various cellular responses including cell cycle arrest, DNA repair and apoptosis. Although detailed insights into the biochemical mechanisms and composition of DNA repair pathways have ...

Crystal structure of ATP-dependent DNA ligase from Rhizobium phage vB_RleM_P10VF
DNA ligases are foundational molecular-biological tools used for cloning and sequencing workflows, and are essential replicative enzymes for all cellular life forms as well as many viruses and bacteriophage. There is considerable interest in structurally and functionally characterizing novel DNA ligases and profiling their ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Fission yeast 26S proteasome mutants are multi-drug resistant due to stabilization of the pap1 transcription factor [PDF]
Here we report the result of a genetic screen for mutants resistant to the microtubule poison methyl benzimidazol-2-yl carbamate (MBC) that were also temperature sensitive for growth.

We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Finding novel vulnerabilities of hypomorphic BRCA1 alleles
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have
