heavy meromyosin การใช้

• Following digestion, two types of meromyosin are formed : heavy meromyosin ( HMM ) and light meromyosin ( LMM ).
• Heavy meromyosin is a protein chain terminating in a globular ATP binding site ( myosin ATPase ) that determines the rate of muscle contraction when muscle is stretched.
• Hepler identified actin microfilaments in bundles at the ectoplasm-endoplasm interface of " Nitella " internodal cells by showing that the bundles bound heavy meromyosin, giving the characteristic arrowhead arrangement.
