Dynein vs. Kinesin

Dyneinnoun

(enzyme) Any of a group of enzymes that hydrolyze ATP and thus provide motive power for motile structures such as microtubules.

Dynein

Dynein is a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work.

Kinesinnoun

(protein) Any of a class of proteins that convert chemical into mechanical energy and power the movement of vesicles and organelles along microtubules

Kinesin

A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments, and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases, a type of enzyme).
