1. Fragments of the myosin protein molecule produced by partial proteolytic digestion, consisting of the head and neck regions (heavy meromyosin) or the tail region (light meromyosin).
Usage: biochemistry; plural form of meromyosin; technical term used in muscle physiology and protein research

Examples

• Meromyosins are important tools in studying the structure and function of muscle proteins.
• Heavy meromyosins retain the ATPase activity of intact myosin molecules.
• Researchers used meromyosins to understand how myosin interacts with actin filaments.
• Light meromyosins form the backbone of the thick filament in muscle tissue.
• The isolation of meromyosins helped scientists elucidate the mechanism of muscle contraction.
