RUBISCO FROM CHLAMYDOMONAS REINHARDTII

The structure was published by Taylor, T.C., Backlund, A., Bjorhall, K., and Andersson, R.J.Spreitzeri., in 2001 in a paper entitled "First Crystal Structure of Rubisco from a Green Alga, Chlamydomonas Reinhardtii" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.4 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 RIBULOSE-1,5 BISPHOSPHATE CARBOXYLASE LARGE CHAIN and RIBULOSE BISPHOSPHATE CARBOXYLASE SMALL CHAIN 1.

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.
