1 Rapid mixing of the Mg2-TnC-pyr-TnI complex with Ca2+ yields similar results, suggesting that the type of metal ion present at the high-affinity sites has little, if any, effect on the probe. MG2 tenascin Oryctolagus cuniculus
2 Our results suggest that a Ca2+-induced structural change in the TnI-binding region of TnC could be transmitted to TnT by affecting the TnT-binding region of TnI as part of the chain of events in the regulation of muscle contraction. Trinitrotoluene tenascin Oryctolagus cuniculus
