2fp4 Summary


Crystal structure of pig GTP-specific succinyl-CoA synthetase in complex with GTP

The structure was published by Fraser, M.E., Hayakawa, K., Hume, M.S., Ryan, D.G., and Brownie, E.R., in 2006 in a paper entitled "Interactions of GTP with the ATP-grasp Domain of GTP-specific Succinyl-CoA Synthetase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.08 Å and deposited in 2006.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Succinyl-CoA ligase [GDP-forming] alpha-chain, mitochondrial and Succinyl-CoA ligase [GDP-forming] beta-chain, mitochondrial.

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 heterodimers.
