1top Summary



The structure was published by Satyshur, K.A., Pyzalska, D., Greaser, M., Rao, S.T., and Sundaralingam, M., in 1994 in a paper entitled "Structure of chicken skeletal muscle troponin C at 1.78 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.78 Å and deposited in 1993.

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

The PDB entry contains the structure of TROPONIN C. This molecule has the UniProt identifier P02588 (TNNC2_CHICK)search. The sample contained 162 residues which is 99% of the natural sequence. Out of 162 residues 162 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 is most likely monomeric.
