1gsa Summary



The structure was published by Hara, T., Kato, H., Katsube, Y., and Oda, J., in 1996 in a paper entitled "A pseudo-michaelis quaternary complex in the reverse reaction of a ligase: structure of Escherichia coli B glutathione synthetase complexed with ADP, glutathione, and sulfate at 2.0 A resolution." (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 GLUTATHIONE SYNTHETASE. This molecule has the UniProt identifier P04425 (GSHB_ECOLI)search. The sample contained 316 residues which is 100% of the natural sequence. Out of 316 residues 314 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
