THE STRUCTURE OF TYPE I 3-DEHYDROQUINATE DEHYDRATASE FROM SALMONELLA TYPHI

The structure was published by Gourley, D.G., Shrive, A.K., Polikarpov, I., et al., Hawkins, A.R., Isaacs, N.W., and Sawyer, L., in 1999 in a paper entitled "The two types of 3-dehydroquinase have distinct structures but catalyze the same overall reaction." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1999.

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 DEHYDRATASE).

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.
