    GO ID   Ontology GO Term Definition
    16459   Myosin Complex  A Protein Complex Formed of One or More Myosin Heavy Chains Plus Associated Light Chains and Other Proteins That Functions As a Molecular Motor; Uses the Energy of ATP Hydrolysis to Move Actin Filaments or to Move Vesicles or Other Cargo On Fixed Actin Filaments; Has Magnesium Atpase Activity and Binds Actin. Myosin Classes Are Distinguished Based On Sequence Features of the Motor or Head Domain But Also Have Distinct Tail Regions That Are Believed to Bind Specific Cargoes. 
    3774   Motor Activity  Catalysis of Movement Along a Polymeric Molecule Such As a Microfilament or Microtubule Coupled to the Hydrolysis of a Nucleoside Triphosphate. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator.
