2dln Summary



The structure was published by Fan, C., Moews, P.C., Walsh, C.T., and Knox, J.R., in 1994 in a paper entitled "Vancomycin resistance: structure of D-alanine:D-alanine ligase at 2.3 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1994.

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

The PDB entry contains the structure of D-ALANINE--D-ALANINE 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.
