|Crystal Structure of the Citrobacter freundii Dihydroxyacetone Kinase Reveals an Eight-stranded a-Helical Barrel ATP-binding Domain|
This is the nucleotide binding domain of the dihydroxyacetone kinase of Citrobacter freundii complexed with AMPPNP (red) and a phospholipid (green). Met and Phe (yellow) separate the nucleotide-binding depression from the lipid-binding pocket of the eight-helix barrel. Homologous domains occur in the PTS-dependent kinase of E.coli and proteins associated with various transcription factors.
