Hypothesis-generating for myosin energetics in cardiac contraction; leaves open validation before any clinical relevance.

Key Points

Investigate the structural conformations and dynamics of myosin subfragment-1 bound to nucleotide complexes using phosphorus-31 nuclear magnetic resonance spectroscopy.
Applied phosphorus-31 nuclear magnetic resonance (31P NMR) spectroscopy to analyze myosin subfragment-1 complexed with nucleotides.
Monitored chemical shifts and resonance peaks of nucleotide phosphorus atoms to detect conformational variations in the protein complex.
Detected distinct phosphorus-31 NMR spectral signatures indicating the presence of two separate conformational states for myosin subfragment-1 nucleotide complexes.
Demonstrated that the equilibrium between these two structural states reflects critical intermediate steps in the actomyosin ATPase cycle.
