title: 3-Methylhistidine content and pH dependency of ATPase activity of adult and embryonic chicken cardiac ventricular myosins.
abstract: A distinct difference in the 3-methylhistidine (3-MeHis) content and the pH-dependency curve for calcium-activated adenosine triphosphatase (Ca-ATPase) activity was observed between chicken and mammalian cardiac ventricular myosins. The 3-MeHis content and pH dependency of the Ca-ATPase activity of myosins from adult and embryonic chicken cardiac ventricular muscles and chicken fast white and slow red muscles were almost the same.
