CALCIUM-BOUND E41A MUTANT OF THE N-DOMAIN OF CHICKEN TROPONIN C, NMR, 40 STRUCTURES

The structure was published by Gagne, S.M., Li, M.X., and Sykes, B.D., in 1997 in a paper entitled "Mechanism of direct coupling between binding and induced structural change in regulatory calcium binding proteins." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1997.

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 90 residues which is < 90% of the natural sequence. Out of 90 residues 90 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.
