1cqj Summary



The structure was published by Joyce, M.A., Fraser, M.E., James, M.N., Bridger, W.A., and Wolodko, W.T., in 2000 in a paper entitled "ADP-binding site of Escherichia coli succinyl-CoA synthetase revealed by x-ray crystallography." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 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 SUCCINYL-COA SYNTHETASE ALPHA CHAIN and SUCCINYL-COA SYNTHETASE BETA CHAIN.

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 heterotetramers.
