THE CRYSTAL STRUCTURE OF RUBISCO FROM ALCALIGENES EUTROPHUS TO 2.7 ANGSTROMS.

The structure was published by Hansen, S., Vollan, V.B., Hough, E., and Andersen, K., in 1999 in a paper entitled "The crystal structure of rubisco from Alcaligenes eutrophus reveals a novel central eight-stranded beta-barrel formed by beta-strands from four subunits." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 1998.

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

This PDB entry contains a complex of 2 biomacromolecules, namely PROTEIN (RIBULOSE BISPHOSPHATE CARBOXYLASE LARGE CHAIN) and PROTEIN (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.
