CRYSTAL STRUCTURE OF AN A/B-DNA INTERMEDIATE CATGGGCCCATG
Overview
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.
