The crystal structure of dihydrodipicolinate synthase from Escherichia coli at 2.5 A resolution.
C.Mirwaldt, I.Korndörfer, R.Huber.
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 > 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.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
