Incorporation of Thymine into Prototrophic and Thymine-dependent Mutants of Bacillus anthracis [PDF]

Journal of General Microbiology, 1969
SUMMARY: Mutants of Bacillus anthracis which were prototrophic in a defined medium below 32° required either thymidine (mutant thy) or low concentration of thymine (mutant thytlr) for growth at 37°. No thymidylate synthetase was produced by these mutants at 37°. Normal enzyme activity was found in bacteria grown at 25°.

Chemically Fueled Systems Chemistry Across Length Scales

Advanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Mercury^II-Mediated Formation of Thymine−Hg^II−Thymine Base Pairs in DNA Duplexes [PDF]

, 2016
The very specific binding of the HgII ion unexpectedly and significantly stabilizes naturally occurring thymine−thymine base mispairing in DNA duplexes. Following this finding, we prepared DNA duplexes containing metal-mediated base pairs at the desired ...

Expression and the Peculiar Enzymatic Behavior of the Trypanosoma cruzi NTH1 DNA Glycosylase. [PDF]

PLoS ONE, 2016
Trypanosoma cruzi, the etiological agent of Chagas' disease, presents three cellular forms (trypomastigotes, epimastigotes and amastigotes), all of which are submitted to oxidative species in its hosts. However, T.

Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

Advanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...

Photocrosslinking Probes Proximity of Thymine Modifiers Tethering Excitonically Coupled Dye Aggregates to DNA Holliday Junction

Molecules, 2022
A DNA Holliday junction (HJ) has been used as a versatile scaffold to create a variety of covalently templated molecular dye aggregates exhibiting strong excitonic coupling. In these dye-DNA constructs, one way to attach dyes to DNA is to tether them via

Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy

Advanced Science, EarlyView.
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...

Conformationally controlled, thymine-based alpha-nucleopeptides [PDF]

, 2009
Rigid peptide backbones and backbone-to-side chain H-bonds permit the design of a-nucleopeptides with known 3D-structure; thymine–thymine base pairing is also ...

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

Angewandte Chemie, EarlyView.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).
