1bh2 Summary



The structure was published by Posner, B.A., Mixon, M.B., Wall, M.A., Sprang, S.R., and Gilman, A.G., in 1998 in a paper entitled "The A326S mutant of Gialpha1 as an approximation of the receptor-bound state." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1998.

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

The PDB entry contains the structure of GUANINE NUCLEOTIDE-BINDING PROTEIN. This molecule has the UniProt identifier P10824 (GNAI1_RAT)search. The sample contained 315 residues which is < 90% of the natural sequence. Out of 315 residues 315 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.
