  • Title: Localization of g2 light chain in the link between the heads and tail of cardiac myosin.
    Author: Kuwayama H, Yagi K.
    Journal: J Biochem; 1980 Jun; 87(6):1603-7. PubMed ID: 7400112.
    Abstract:
    Cardiac myosin liberated 1.99 mol of acetate per mol after acid hydrolysis. The myosin subfragment-1, which cannot bind g2 light chain, liberated 0.85-1.16 mol of acetate per mol. On the other hand, negligible amounts of acetate could be detected from g1 and g2 light chains. The acetates, which were measured by a microenzymic method, were derived from the acetylated N-terminal of the heavy chain. It was concluded that g2 light chain is bound to the C-terminal region of subfragment-1, which is the link between the heads and tail of myosin.
