Isolation of myosin from starfish sperm heads.

Mabuchi I .


???displayArticle.abstract???
Myosin was extracted and partially purified from the head portion of spermatozoa of the starfish, Asterias amurensis. The sperm myosin showed a specific Ca2+-activated ATPase [EC 3.6.1.3] activity of 0.2 mumoles Pi/min/mg at high ionic strength and pH 6.5. It resembled egg myosin in forming thick filaments, becoming attached to actin filaments. subunit composition, and serological properties.
