COMPLEX OF D-ALA:D-ALA LIGASE WITH ADP AND A PHOSPHORYL PHOSPHONATE

The structure was published by Fan, C., Park, I.S., Walsh, C.T., and Knox, J.R., in 1997 in a paper entitled "D-alanine:D-alanine ligase: phosphonate and phosphinate intermediates with wild type and the Y216F mutant." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1996.

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

The PDB entry contains the structure of D-ALA\:D-ALA LIGASE. This molecule has the UniProt identifier P07862 (DDLB_ECOLI)search. The sample contained 306 residues which is 100% of the natural sequence. Out of 306 residues 306 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 is most likely monomeric.
