CRYSTAL STRUCTURE OF UNACTIVATED TOBACCO RUBISCO WITH BOUND PHOSPHATE IONS

The structure was published by Duff, A.P., Andrews, T.J., and Curmi, P.M.G., in 2000 in a paper entitled "The transition between the open and closed states of rubisco is triggered by the inter-phosphate distance of the bound bisphosphate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.45 Å and deposited in 2000.

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

This PDB entry contains a complex of 2 biomacromolecules, namely RUBISCO (LARGE SUBUNIT) and RUBISCO (SMALL SUBUNIT).

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 most likely quaternary structure is a 16meric assembly.
