Myosin - Wikipedia
网页Myosins (/ ˈmaɪəsɪn, - oʊ -/ [1][2]) are a family 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. The first myosin (M2) to be discovered was in 1864 by Wilhelm Kühne.
Actin and Myosin - Biology Dictionary
网页2021年2月7日 · Actin and myosin are both proteins that are found in every type of muscle tissue. Thick myosin filaments and thin actin filaments work together to generate muscle contractions and movement. Myosin is a type of molecular motor and converts chemical energy released from ATP into mechanical energy.
Actin, Myosin, and Cell Movement - The Cell - NCBI Bookshelf
网页Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has provided the model for understanding actin-myosin interactions and the motor activity of myosin molecules.
Myosin - an overview | ScienceDirect Topics
网页Myosin is the predominantly expressed protein in muscle and serves as the molecular motor responsible for muscle contraction. It is also involved in actin-based cellular motility. Myosin has been extensively studied in biochemistry, and its enzymatic pathway and mechanism have been determined through rapid reaction studies.

网页Myosins are cytoskeletal motor proteins that use energy derived from ATP hydrolysis to generate force and movement along actin filaments.
Fundamental Properties and Structure of Myosin | SpringerLink
网页2021年8月24日 · The term myosin was originally used to describe the protein responsible for force generation in the thick filaments of striated and smooth muscle cells. Eventually, nonmuscle myosins with similar properties (including the ability to form thick filaments) were purified from other eukaryotic cells.
