Bioinspired Crystallization of Guanine

The Journal of Physical Chemistry Letters, 2021
Biological guanine crystals in organisms exhibit excellent optical properties and functions, including broad-band and narrow-band reflectors, band-tunable reflectors, mirrors, and stimuli-responsive structural colors, attributed to the high refractive index of guanine (1.85) and the exquisite control of the polymorphs, morphologies, sizes, exposed ...

Microhydration of the Guanine−Guanine and Guanine−Cytosine Base Pairs

The Journal of Physical Chemistry A, 2010
Monohydration structures of the guanine-guanine and guanine-cytosine base pairs have been elucidated by IR-UV double resonance spectroscopy combined with ab initio calculations. The systems studied consist of the homodimer of 9-methylguanine and the heterodimer of 9-methylguanine and 1-methylcytosine in which the methyl group is introduced to mimic the

Conserved guanine-guanine stacking in tetraplex and duplex DNA

European Biophysics Journal, 2001
Using a series of suitably chosen oligonucleotides, we demonstrate that the DNA duplex of d(CCCCGGGG) provides an almost identical CD spectrum as the parallel-stranded tetraplex of d(GGGG). The CD spectra are very sensitive to base stacking in DNA so that the above observation indicates that guanine-guanine stacking is essentially the same within the ...

Metabolism of Guanine and Guanine Nucleotides in Primary Rat Cardiomyocyte Cultures

Biochemical and Molecular Medicine, 1991
The metabolic fate of labeled guanine and of prelabeled guanine nucleotides (GuRN) was studied in cultured rat cardiomyocytes. Special attention was given to guanine salvage in comparison to degradation; to the contribution of GuRN to adenine nucleotides (AdRN); to the fluxes from GMP to IMP and from IMP to GMP; and to the degradation pathways of GuRN.
