Thymine Incorporation and Metabolism by Various Classes of Thymine-less Bacteria [PDF]
Journal of General Microbiology, 1965 SUMMARY: Escherichia coli strain 15T- yielded 109 organisms from 1 μg. thymine and growth was continuous, not diphasic. Aminopterin-selected thymine-less bacteria, on the other hand, required 20-25 μg. thymine/ml. to sustain growth, although thymine incorporation was the same as for strain 15T-, approximately 10-9 μg./bacterium.

Joining Nanotubes Comprising Nucleobase-carrying Amphiphilic Polypeptides
CHIMIA, 2018 Three kinds of amphiphilic polypeptides, X-poly(sarcosine)-b-(L-Leu-Aib)6 (X = adenine, thymine, glycolic acid), were synthesized and self-assembled in a tris buffer to take on nanotube morphology.

British Journal of Clinical Pharmacology, EarlyView.While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

Covalent Attachment of a Platinum(II) Complex inside DNA Duplexes
ChemistryEurope, EarlyView.Oxidative addition is used for the site‐specific incorporation of an organometallic PtII complex as an artificial nucleobase into a DNA duplex. The platination stabilizes the duplex and confers it with phosphorescence. An organometallic phosphorescent PtII complex is introduced into DNA duplexes via oxidative addition to a tailor‐made artificial ...

Interactions of some metal ions with Nitrogenous bases present in Nucleotides
مجلة بغداد للعلوم, 2007 Acidity constants at 30co and 0.125 ionic strength have been determined for the Nitrogous bases of nucleic acid; cytocine, uarcil and thymine, and found to be 3.55 x10-19 , 1.44 x10 -19 and 7.24 x10 -20 respectively.

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy
Chemistry – A European Journal, EarlyView.Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Stabilization of Long-Looped i-Motif DNA by Polypyridyl Ruthenium Complexes
Frontiers in Chemistry, 2019 A spectroscopic study of the interactions of Λ- and Δ-[Ru(phen)2(dppz)]2+ with i-motif DNA containing thymine loops of various lengths. In the presence of i-motifs, the luminescence of the Λ enantiomer was enhanced much more than the Δ. Despite this, the

Chemistry – A European Journal, EarlyView.A compact C4N4 fluorophore—comprising only four carbons and four nitrogens—shows structure‐dependent fluorescence that can be rationalized by TDDFT and AFIR analyses. Rational structural design controls whether emission is turned ON or OFF through computationally identified CI structures.
