The solution structure of a cardiac troponin C-troponin I-troponin T complex shows a somewhat compact troponin C interacting with an extended troponin I-troponin T component.
We have investigated the structure of the cTnC-cTnI-cTnT(198-298) calcium-saturated, ternary cardiac troponin complex by small-angle scattering with contrast variation. Shape restoration was also applied to the scattering information resulting from the deuterated cTnC subunit, the unlabeled cTnI-cTnT(198-298) subunits, and the entire complex. The experimental results and modeling indicate that ...
متن کاملDephosphorylation specificities of protein phosphatase for cardiac troponin I, troponin T, and sites within troponin T
Protein dephosphorylation by protein phosphatase 1 (PP1), acting in concert with protein kinase C (PKC) and protein kinase A (PKA), is a pivotal regulatory mechanism of protein phosphorylation. Isolated rat cardiac myofibrils phosphorylated by PKC/PKA and dephosphorylated by PP1 were used in determining dephosphorylation specificities, Ca(2+)-stimulated Mg(2+)ATPase activities, and Ca(2+) sensi...
متن کاملHydrodynamic properties of bovine cardiac troponin-I and troponin-T.
Bovine cardiac troponin-I (TN-I) and troponin-T (TN-T) have been examined in solution using ultracentrifugation, gel filtration, and viscosity. A new method of purifying TN-T, employing hydroxylapatite chromatography in 6 M urea, is reported. Cardiac TN-T (Mr = 36,000) undergoes a reversible, concentration-dependent association in nondenaturing buffers, probably to a tetramer. The Stokes radius...
متن کاملPlasma troponin T and troponin I after minimally invasive coronary bypass surgery.
In the last decade, plasma cardiac troponin T (cTnT) and cardiac troponin I (cTnI) have been identified as specific and sensitive markers of myocardial cell injury (1, 2). During most types of cardiac surgery, some degree of myocardial injury regularly occurs that is dependent on multiple factors, such as the type and extent of the surgical procedure, the method of myocardial protection, the pr...
