The 2-naphthol analogue of tyrosine, 2-amino-3-(6-hydroxy-2-naphthyl)propanoic acid (NpOH), has been genetically introduced into proteins in Escherichia coli . This is achieved through the directed evolution of orthogonal aminoacyl-tRNA synthetase/tR

A new method has been developed to reassign the rare codon AGA in Escherichia coli by engineering an orthogonal tRNA/aminoacyl-tRNA synthetase pair derived from Methanocaldococcus jannaschii. The tRNA mutant was introduced with a UCU anticodon, and t

[reaction: see text] Photolysis of 3 in argon-saturated 2-propanol led to formation of 5 via intermolecular H-atom abstraction followed by lactonization. Irradiation of 4 in 2-propanol gave compounds 6 and 7 that also come from intermolecular H-atom

Laser flash photolysis (LFP) of 1-naphthyl azide in glassy 3-methylpentane at 77 K produces singlet 1-naphthylnitrene (362, 383, 397 nm), which relaxes to the lower energy triplet nitrene with kisc = (1.1 ± 0.1) × 107 s-1. LFP of 2-naphthyl azide u

Laser flash photolysis (LFP) of 9-azidoanthracene produces singlet 9-anthrylnitrene (1AN) with λmax = 331, 344, and 412 nm. The lifetime of 1AN is 17 ns at 77 K and is 27 ns at ambient temperature and is controlled by intersystem crossing (ISC) to t

Phenyl azide, 2,6-diethylphenyl azide, 2,6-diisopropylphenyl azide, and 2,4,6-tri-tert-butylphenyl azide were studied by laser flash photolysis (LFP) methods. LFP (266 nm) of the azides in glassy 3-methylpentane at 77 K produces the transient UV-vis

The structures of halogen atom-benzene complexes were investigated by modern DFT and ab initio computational methods. The spectroscopic properties of the complexes are also predicted and are in good agreement with experiment where such data have been

The photoreaction between riboflavin tetraacetate and nucleosides was investigated using time-resolved infrared spectroscopy (TRIR), laser flash photolysis with UV−vis detection, fluorescence quenching, absorption spectroscopy, and density function

Calculations predict that singlet cyclopropylnitrene has a closed-shell configuration, in contrast to singlet phenylnitrene, and has little or no barrier to fragmentation.
