Crystal Structure of apo D-alanine:D-alanine Ligase (Ddl) from Mycobacterium tuberculosis

The structure was published by Bruning, J.B., Murillo, A.C., Chacon, O., Barletta, R.G., and Sacchettini, J.C., in 2011 in a paper entitled "Structure of the Mycobacterium tuberculosis D-Alanine:D-Alanine Ligase, a Target of the Antituberculosis Drug D-Cycloserine." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2010.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of D-alanine--D-alanine ligase.

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.
