title: Aptamer structures from A to zeta.
abstract: Solution structures of RNA aptamers for FMN, ATP, arginine, and citrulline reveal how oligonucleotides can fold to form selective binding pockets for biological cofactors and amino acids. These structures confirm old ideas and provide new insights about three-dimensional structures of nucleic acids and their possible role in chemical reactions.
