2g13 Summary


CsoS1A with sulfate ion

The structure was published by Tsai, Y., Sawaya, M.R., Cannon, G.C., et al., Heinhorst, S., Kerfeld, C.A., and Yeates, T.O., in 2007 in a paper entitled "Structural Analysis of CsoS1A and the Protein Shell of the Halothiobacillus neapolitanus Carboxysome." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.61 Å and deposited in 2006.

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

The PDB entry contains the structure of Major carboxysome shell protein 1A. This molecule has the UniProt identifier P45689 (CSOA_HALNC)search. The sample contained 98 residues which is 100% of the natural sequence. Out of 98 residues 94 were observed and are deposited in the PDB.

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 molecule most likely forms homohexamers.
