CRYSTALLIZATION (Commentary)
ORGANISM
UNIPROT
LITERATURE
hanging drop method of vapor diffusion using a sparse matrix screen. Two crystal structures: a site-directed mutant protein (K186A) complexed with GDP-perosamine and the wild-type enzyme complexed with an unnatural ligand, GDP-3-deoxyperosamine. These structures, determined to 1.6 and 1.7 A resolution, respectively
the three-dimensional structure of the enzyme is determined to a nominal resolution of 1.8 A and refined to an R-factor of 17.9%. Each subunit of the dimeric enzyme contains a seven-stranded mixed beta-sheet, a two-stranded antiparallel beta-sheet, and 12 alpha-helices
