Crystal structure of A Pantothenate synthetase complexed with ATP

The structure was published by Wang, S. and Eisenberg, D., in 2006 in a paper entitled "Crystal Structure of the Pantothenate Synthetase from Mycobacterium tuberculosis, Snapshots of the Enzyme in Action." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.55 Å and deposited in 2005.

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

The PDB entry contains the structure of Pantoate--beta-alanine ligase. This molecule has the UniProt identifier P9WIL5 (PANC_MYCTU)search. The sample contained 300 residues which is 96% of the natural sequence. Out of 300 residues 277 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.
