Interactions of Mn2+ with a non-self-complementary Z-type DNA duplex.
Crystal structures of the hexanucleotide d(CACGCG)·d(CGCGTG) were determined in two crystal lattices when different concentrations of the counterion Mn2+ were used in crystallization. The availability of Mn2+ during the crystallization process appears to play an important role in inducing different crystal packings that lead to crystals belonging to the two space groups P2(1) and P6(5). Analysis of the molecular interactions of Mn2+ with the Z-form duplexes shows direct coordination to the purine residues G and A.
期刊介绍:
Acta Crystallographica Section F is a rapid structural biology communications journal.
Articles on any aspect of structural biology, including structures determined using high-throughput methods or from iterative studies such as those used in the pharmaceutical industry, are welcomed by the journal.
The journal offers the option of open access, and all communications benefit from unlimited free use of colour illustrations and no page charges. Authors are encouraged to submit multimedia content for publication with their articles.
Acta Cryst. F has a dedicated online tool called publBio that is designed to make the preparation and submission of articles easier for authors.
