Question

Actin binding sites are located on: (A) Troponin (B) Tropomyosin (C) Meromyosin (D) Both tropomyosin and meromyosin

Tardigrade Admin · Accepted Answer

Myosin has two fragments, light meromyosin (LMM) and heavy meromyosin (HMM). HMM consists of two globular sub fragments (S-l) and one rod shaped fibrous sub fragment (S-2). Each S-l segment contains an ATPase site and a binding site for actin.
