THE CRYSTAL STRUCTURE OF AMINODEOXYCHORISMATE SYNTHASE FROM PHOSPHATE GROWN CRYSTALS

The structure was published by Parsons, J.F., Jensen, P.Y., Pachikara, A.S., Howard, A.J., Eisenstein, E., and Ladner, J.E., in 2002 in a paper entitled "Structure of Escherichia coli aminodeoxychorismate synthase: architectural conservation and diversity in chorismate-utilizing enzymes." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.05 Å and deposited in 2001.

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

This PDB entry contains multiple copies of the structure of p-aminobenzoate synthase component I.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
