Extent and localization of conformational changes in troponin C caused by calcium binding. Spectral studies in the presence and absence of 6 M urea.

Resultado clave

Calcium binding induces conformational changes in troponin C that were evaluated via spectral studies in the presence and absence of 6 M urea.

Puntos clave

• The study aims to investigate the conformational changes in troponin C (TnC) caused by calcium binding and the influence of urea.
• TnC was prepared and its concentrations determined using absorbance differences in tyrosine.
• Spectral studies were conducted to assess changes in TnC structure with and without 6 M urea.
• The binding of calcium to TnC induced significant conformational alterations.
• Urea presence affected the extent of these structural changes, suggesting a stabilizing effect on TnC.
