CRYSTAL STRUCTURE OF DEHYDROQUINATE SYNTHASE (DHQS) COMPLEXED WITH CARBAPHOSPHONATE, NAD+ AND ZN2+

The structure was published by Carpenter, E.P., Hawkins, A.R., Frost, J.W., and Brown, K.A., in 1998 in a paper entitled "Structure of dehydroquinate synthase reveals an active site capable of multistep catalysis." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

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

This PDB entry contains multiple copies of the structure of PROTEIN (3-DEHYDROQUINATE SYNTHASE).

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.
