CRYSTAL STRUCTURE OF A TERNARY COMPLEX OF E. COLI DIHYDROPTEROATE SYNTHASE

The structure was published by Achari, A., Somers, D.O., Champness, J.N., Bryant, P.K., Rosemond, J., and Stammers, D.K., in 1997 in a paper entitled "Crystal structure of the anti-bacterial sulfonamide drug target dihydropteroate synthase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1997.

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

The PDB entry contains the structure of DIHYDROPTEROATE SYNTHASE. This molecule has the UniProt identifier P0AC13 (DHPS_ECOLI)search. The sample contained 282 residues which is 100% of the natural sequence. Out of 282 residues 282 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.
