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

A vascularized liver‐on‐a‐microsphere system is developed to recreate lobule‐like cellular organization and endothelial barrier function within compartmentalized hydrogel particles. The platform enhances hepatic performance and reveals alanine‐glucose cycle activation linked to improved detoxification capacity, offering a high‐throughput microscale ...

Flavin Catalysts in Organic Synthesis
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Photoinduced Formation Mechanism of the Thymine–Thymine (6–4) Adduct
The photoinduced mechanism leading to the formation of the thymine–thymine (6–4) photolesion has been studied by using the CASPT2//CASSCF approach over a dinucleotide model in vacuo.

pH‐Driven Actuation of Unmodified DNA Origami Rectangles
Unmodified DNA origami rectangles exhibit a reversible transition between planar and tubular states driven by near‐neutral pH changes. This behavior arises from crossover‐mediated mechanical coupling of overwound DNA and extends to dimers and nanoribbons, enabling the formation of nanotube architectures without added motifs or chemical modification ...

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

Time Resolved DNA Barcodes for Information Encoding and Dynamic Encryption
This study establishes a molecular information platform based on DNA Temporal Barcodes. Information is encoded through combinations of DNA tags with distinct retention times, while dynamic encryption is achieved through a key‐triggered DNA ligation.
