Native Myosin

Specification

• Cat#: THP-170
• Product Name: Native Myosin
• Description: Myosin is the principal protein of the myofilaments in muscle. Along with actin, it is involved in muscle contraction. Myosin, from several species, has been purified and characterized. Recent studies on highly purified myosin indicate that it has a molecular weight of about 500,000. Purified myosin preparations have the capacity to hydrolyze the terminal phosphate group from adenosine triphosphate (ATP). The ATPase activity of myosin is stimulated by Ca2+ and it has two pH optima, one at pH 6.0 and the other at pH 9.5. The reaction is also influenced by KCl concentration. In addition to ATP, myosin can also hydrolyze the terminal phosphate groups from cytidine triphosphate (CTP), guanosine triphosphate (GTP) and inosine triphosphate (ITP).
• Molecular Weight: it has a molecular weight of about 500,000.
• Optimal pH: PH 6.0;PH 9.5
