Question

During evolution of the myosin superfamily different myosins diverged in such a way that each is adapted to the specific task that it carries out. In lecture we discussed three properties of myosin motors that vary among family members that underwent adaptation. What are those properties?

Answer 1

Three properties of myosin motors are a step size, duty ratio, and tail interactions.

Step-by-step explanation:

• Myosin is an actin motor protein.

• The primary function of the myosin is to convert ATP to energy. Duty is the fraction of ATP cycle to actin.

• Step size means displacement during 1 ATP cycle. Step size of myosin was found out by measuring the velocity of different filament size of myosis.

• Muscles contraction, chemo taxis, cytokinesis is some function that can be related with among the family.
