3237578-2	1988	Because one mole of actin purified from the red and white muscles of Leghorn chickens and one mole of myosin contain respectively one and two moles of N tau-methylhistidine, and the molar ratio of myosin and actin in skeletal muscle is known to be 1:6, the myofibrillar myosin and actin contents of avian skeletal muscles can be determined from the amounts of protein-bound N tau-methylhistidine found in acid hydrolysates of this tissue.	3-methylhistidine	151-172	myosin, heavy chain 15	Gallus gallus	102-108
