==Overview==
<references/>
The crystal structure of dihydrodipicolinate synthase from E. coli was determined by multiple isomorphous replacement methods. The structure was refined at a resolution of 2.5 A and the final R-factor is 19.6% for 32,190 reflections between 10.0 A and 2.5 A and F &gt; 2 sigma (F). The crystallographic asymmetric unit contains two monomers related by approximate 2-fold symmetry. A tetramer with approximate 222 symmetry is built up by crystallographic symmetry. The tetramer is almost planar with no contacts between the subunits related by the non-crystallographic dyad. The active sites are accessible from a wide water-filled channel in the center of the tetramer. The dihydrodipicolinate synthase monomer is composed of two domains. Each polypeptide chain is folded into an 8-fold alpha/beta barrel and a C-terminal alpha-helical domain comprising residues 224 to 292. The fold is similar to that of N-acetylneuraminate lyase. The active site lysine 161 is located in the alpha/beta barrel and has access via two entrances from the C-terminal side of the barrel.
