ACTIVATED SPINACH RUBISCO IN COMPLEX WITH ITS SUBSTRATE RIBULOSE-1,5-BISPHOSPHATE AND CALCIUM

The structure was published by Taylor, T.C. and Andersson, I., in 1997 in a paper entitled "The structure of the complex between rubisco and its natural substrate ribulose 1,5-bisphosphate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1996.

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

This PDB entry contains a complex of 2 biomacromolecules, namely RIBULOSE BISPHOSPHATE CARBOXYLASE/OXYGENASE.

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.
