Publication Abstract from PubMed
The DNA dodecamer CATGGGCCCATG in a crystal structure of resolution 1.3 A has a conformation intermediate between A and B DNA. This trapping of a stable intermediate suggests that the A and B DNA families are not discrete, as previously believed. The structure supports a base-centered rather than a backbone-centered mechanism for the A <--> B transition mediated by guanine tracts. Interconversion between A and B DNA provides another means for regulating protein-DNA recognition.
