Answer:

Eukaryotic flagella and cilia have attracted the attention of many researchers over the last century, since they are highly arranged organelles and show sophisticated bending movements. Two important cytoskeletal and motor proteins, tubulin and dynein, were first found and described in flagella and cilia. Half a century has passed since the discovery of these two proteins, and much information has been accumulated on their molecular structures and their roles in the mechanism of microtubule sliding, as well as on the architecture, the mechanism of bending movement and the regulation and signal transduction in flagella and cilia. Historical background and the recent advance in this field are described.

Answer:

The enzymatic protein in flagella is Dynein protein.  

Explanation:

Dynein Protein:

  • A family of cytoskeletal motor proteins called Dynein's propels cells along microtubules. They transform the ATP's chemical energy into mechanical work.
  • Transporting different cellular cargos, providing pressures and displacements necessary for mitosis, and powering the beat of eukaryotic cilia and flagella are all functions of dynein.
  • All of these activities are referred to as "minus-end directed motors" because they all depend on dynein's capacity to travel retrogradely, or in the direction of the minus end of the microtubules.
  • Anterograde transport, in contrast, refers to the movement of most kinesin motor proteins in the direction of the plus-end of the microtubules.
  • An eukaryotic cell uses ATP to power the movement of its cilia and flagella, which are then hydrolyzed into ADP + Pi by the activation of the dynein protein.
  • Animals have the myosin protein, which stops the movement of microtubules, in their muscles. It is found in cilia and flagella.
  • In flagella, the protein known as flagellin is present and is responsible for the structure.
  • Similar to how muscle cells use actin and myosin as well as ATP hydrolysis for movement, the cillia and flagella's axonemes contain dynein proteins that aid in their beating and transfer chemical energy from ATP hydrolysis to mechanical energy.
