Crystal structure of D-alanine-D-alanine ligase A from Xanthomonas oryzae pathovar oryzae with ADP

The structure was published by Doan, T.T.N., Kim, J.K., Ahn, Y.J., and Kang, L.W., in in a paper entitled "Crystal structure of D-alanine-D-alanine ligase A from Xanthomonas oryzae pathovar oryzae with ADP" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2011.

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

The PDB entry contains the structure of D-alanine--D-alanine ligase 1. This molecule has the UniProt identifier Q2P8P8 (Q2P8P8_XANOM)search. The sample contained 384 residues which is 100% of the natural sequence. Out of 384 residues 344 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.
