Structure of the fibre-forming protein pilin at 2.6 angstrom resolution
Article Abstract:
The fiber-forming protein, pilin, contains a crystallographic structure having an alpha-beta roll fold with an O-attached disaccharide and an alpha-helical spine of 85 angstroms. The helical assembly forms centrally coiled alpha-1 helices marked by beta-sheets. The constraints are stabilized by arranging the sequence conserved flat face of the one pilin subunit with the alpha-1 helical tail of another. Monomer and dimer substrates form distinct fiber models. The molecular characteristics of pilin are discussed.

Resurrecting a broken genome
Article Abstract:
A mighty bacterium Deinococcus radiodurans that manages to rebuild its shattered chromosomes is revealed. It shows that the independent and recurrent evolution of resistance to radiation and desiccation in bacteria raises the theory that these unusual properties do not require any fundamentally distinct mechanism, but only a little adjusting of basic biological mechanisms already present.

A light-sensing knot revealed by the structure of the chromophore-binding domain of phytochrome
Article Abstract:
The three-dimensional structure of the chromophore-binding domain of Deinococcus radiodurans phytochrome assembled with its chromophore biliverdin in the Pr ground state is described. The structure provides the first three-dimensional glimpse into the photochromic behavior of photoreceptors and helps to explain the evolution of higher plant phytochromes from prokaryotic percursors.
