Crystal structure of a chaperone-bound assembly intermediate of form I Rubisco

The structure was published by Bracher, A., Starling-Windhof, A., Hartl, F.U., and Hayer-Hartl, M., in 2011 in a paper entitled "Crystal structure of a chaperone-bound assembly intermediate of form I Rubisco." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 2011.

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 RbcX protein.

The most likely quaternary structure is a 24meric assembly.
