Thus it appears that the actin-binding site around the two thiols found in skeletal myosin is common to different types of myosin.doi:10.1016/0167-4838(87)90259-7Rie SuzukiFumi MoritaElsevier B.V.Biochim Biophys Acta

which are able to convert chemical energy of ATP into mechanical work (Figure 4). The myosin molecule consists of one or two heavy chains containing a motor domain and a cargo-binding tail, and a variable number of light chains. Cycles of ...
The Use of Peptide Mimetics to Define the Actin-Binding Sites on the Head of the Myosin MoleculeDefinition of the molecular mechanisms in muscle contraction and its regulation entails a description of how the components of the organised assembly of proteins first dock with their substrates/partners,...
In the first scenario, we assumed that when exocytosis starts, myosin contracts and pulls the F-actin away from the membrane, as observed in Gauthier et al.15. Consequently, the force generated by actin polymerization ceases. Experimental data show that this is possible in spines since myosin ...
According to automatic annotations performed with the Paramecium database, myosin II is present in the Paramecium genome [27]. The myosin II binding site is quite differentially conserved across P. tetraurelia subfamilies (Fig. 5). Most subfamilies show conservation between 40 to 60%. The ...
