1igs Summary



The structure was published by Hennig, M., Darimont, B., Sterner, R., Kirschner, K., and Jansonius, J.N., in 1995 in a paper entitled "2.0 A structure of indole-3-glycerol phosphate synthase from the hyperthermophile Sulfolobus solfataricus: possible determinants of protein stability." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1995.

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

The PDB entry contains the structure of INDOLE-3-GLYCEROLPHOSPHATE SYNTHASE. This molecule has the UniProt identifier Q06121 (TRPC_SULSO)search. The sample contained 248 residues which is 100% of the natural sequence. Out of 248 residues 247 were observed and are deposited in the PDB.

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 is most likely monomeric.
