UNACTIVATED RUBISCO with OXYGEN BOUND

The structure was published by Stec, B., in 2012 in a paper entitled "Structural mechanism of RuBisCO activation by carbamylation of the active site lysine." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.96 Å and deposited in 2012.

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 large chain and Ribulose bisphosphate carboxylase small chain.

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.
