(5) The more sophisticated computer analysis of the data has revealed a substantial CD contribution from the low-affinity sites (approximately 30% of the high affinity contribution at pH 6.94) and suggests that skeletal TN-C with Ca2+ bound at the low-affinity sites is in a different conformation from that when just the high-affinity sites are occupied, in agreement with a recent nuclear magnetic resonance (NMR) study on this system (Seaman, K. B., Hartshorne, D. J.
