CRYSTAL STRUCTURE OF GCN4-PIQ, A TRIMERIC COILED COIL WITH BURIED POLAR RESIDUES

The structure was published by Eckert, D.M., Malashkevich, V.N., and Kim, P.S., in 1998 in a paper entitled "Crystal structure of GCN4-pIQI, a trimeric coiled coil with buried polar residues." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

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

The PDB entry contains the structure of PROTEIN (GENERAL CONTROL PROTEIN GCN4-PIQ). This molecule has the UniProt identifier P03069 (GCN4_YEAST)search. The sample contained 32 residues which is < 90% of the natural sequence. Out of 32 residues 32 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 most likely forms homotrimers.
