This is a retrospective review on the anniversary of the first X-ray crystal structure of B-DNA dodecamer CGCGAATTCGCG solved by R. Dickerson’s team at UCLA/CIT. Timely established conclusions, drawn from the X-ray crystal structures of DNA oligome

To prevent the precipitation reaction between glycyrrhizin (1) and berberine (3) in the decoctions of Glycyrrhiza/Coptis rhizome or Glycyrrhiza/Phellodendron bark, the presence of cyclodextrin (CD) in the mixture was proven to be effective. The preve

In crystals of complexes of thermine and d(CGCGCG) 2 molecules grown at 4, 10, and 20 °C, the numbers of thermine molecules connected to the DNA molecule were dependent on the temperature of the crystallization. Two molecules of thermine and one Mg

There are many great reports of polyamine stabilization of the Z-DNA by bridge conformation between neighboring, symmetry-related Z-DNA in the packing of crystals. However, polyamine binding to the minor groove of Z-DNA and stabilizing the Z-DNA stru

The Halichondria sponge-derived fungus, Gymnacella dankaliensis, was cultured in two different media conditions. A modified malt extract medium containing soluble starch instead of glucose resulted in two extremely unusual steroids, dankasterones A (

We succeeded in the crystallization of d(CGCGCG){sub 2} and methylamine Complex. The crystal was clear and of sufficient size to collect the X-ray crystallographic data up to 1.0 A resolution using synchrotron radiation. As a result of X-ray crystall
