The Myosin V motor head can be subdivided into the following functional regions: Nucleotide-binding site - These elements together coordinate di-valent metal cations (usually magnesium) and catalyze hydrolysis: Switch I - This contains a highly conserved SSR motif. Isomerizes in the presence of ATP. See more Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP-dependent and responsible for actin-based motility.
