Question

Explain the structure of a meromyosin.​

Answer 1

Answer:

• Meromyosins are composed of many monomeric proteins.

• It consists one thick filament.

• It has 2 parts, Heavy meromyosin (HMM) and light meromyosin (LMM)

• HMM - A globular head with a short arm and a tail.

• The globular head is an active atpase enzyme and it have binding sited for ATP and active sites for actin.

Answer 2

Answer:

♡Each myosin (thick) filament is also a polymerised protein and many monomeric proteins called meromyosins constitute one thick filament.

♡Each head with a short arm and a tail, the former being called the heavy meromyosin (HMM) and the latter, the light meromyosin (LMM).

♡The HMM component, i.e, the head and short arm projects outwards at regular distance.

♡Meromyosin has two important parts, a globular and angle from each other from the surface of a polymerised myosin filament and is known as cross arm.

♡The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for actin.
