crystal structure of human phosphoribosyl pyrophosphate synthetase 1 mutant S132A

The structure was published by Li, S., Lu, Y., Peng, B., and Ding, J., in 2007 in a paper entitled "Crystal structure of human phosphoribosylpyrophosphate synthetase 1 reveals a novel allosteric site" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2006.

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

This PDB entry contains multiple copies of the structure of Ribose-phosphate pyrophosphokinase I.

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 homohexamers.
