Crystal structure of alanine racemase from D-cycloserine producing Streptomyces lavendulae

The structure was published by Noda, M., Matoba, Y., Kumagai, T., and Sugiyama, M., in 2004 in a paper entitled "Structural evidence that alanine racemase from a D-cycloserine-producing microorganism exhibits resistance to its own product." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2004.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of alanine racemase. This molecule has the UniProt identifier Q65YW7 (Q65YW7_STRLA)search. The sample contained 386 residues which is 100% of the natural sequence. Out of 386 residues 382 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
