Three-dimensional reconstruction of rigor insect flight muscle from tilted thin sections.


Journal Article

Rigor cross-bridges show two conformations paired within each 38.7-nm axial repeat. The two forms may express two stages of the cross-bridge cycle during contraction. Differing numbers of myosin heads per cross-bridge and associated helical changes in the thin filament distinguish the two forms and suggest that both myosin heads usually bind to a single thin filament.
