Crystal Structure of Activated Ribulose-1,5-bisphosphate Carboxylase/oxygenase (Rubisco) from Green alga, Chlamydomonas reinhardtii Complexed with 2-Carboxyarabinitol-1,5-bisphosphate (2-CABP)

The structure was published by Mizohata, E., Matsumura, H., Okano, Y., et al., Inoue, T., Yokota, A., and Kai, Y., in 2002 in a paper entitled "Crystal structure of activated ribulose-1,5-bisphosphate carboxylase/oxygenase from green alga Chlamydomonas reinhardtii complexed with 2-carboxyarabinitol-1,5-bisphosphate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.84 Å and deposited in 2001.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Large subunit of Rubisco and Small subunit of Rubisco.

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.
