1k0g Summary



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.
