title: The ribonucleotide reductase jigsaw puzzle: a large piece falls into place.
abstract: The three-dimensional structure of ribonucleotide reductase protein R1 from Escherichia coli reveals a novel 10-stranded alpha/beta barrel fold. A long loop penetrates the center cavity to assemble the active site cysteine triad.
