STRUCTURE OF A SARCOPLASMIC CALCIUM-BINDING PROTEIN FROM AMPHIOXUS REFINED AT 2.4 ANGSTROMS RESOLUTION

The structure was published by Cook, W.J., Jeffrey, L.C., Cox, J.A., and Vijay-Kumar, S., in 1993 in a paper entitled "Structure of a sarcoplasmic calcium-binding protein from amphioxus refined at 2.4 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 1993.

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

The PDB entry contains the structure of SARCOPLASMIC CALCIUM-BINDING PROTEIN. This molecule has the UniProt identifier P04570 (SCP2_BRALA)search. The sample contained 185 residues which is 100% of the natural sequence. Out of 185 residues 185 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 homodimers.
