Study Notes
Myosin Composition
- Myosin is a hexameric protein composed of two heavy chains and four light chains.
Role of Amino Terminus
- The amino terminus of myosin is the head region, which binds to actin and has ATPase activity.
Thick Filaments
- Thick filaments in muscle cells are formed by the assembly of myosin molecules.
Thin Filaments
- Thin filaments in muscle cells are formed by the assembly of actin molecules.
