1qdl Summary



The structure was published by Knochel, T., Ivens, A., Hester, G., et al., Wilmanns, M., Kirschner, K., and Jansonius, J.N., in 1999 in a paper entitled "The crystal structure of anthranilate synthase from Sulfolobus solfataricus: functional implications." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1999.

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

This PDB entry contains a complex of 2 biomacromolecules, namely PROTEIN (ANTHRANILATE SYNTHASE (TRPE-SUBUNIT)) and PROTEIN (ANTHRANILATE SYNTHASE (TRPG-SUBUNIT)).
