Popis: The inhibiting effect of Pb2+ (0.1-1.0 mM) on superprecipitation and ATPase activity of myometrium actomyosin has been shown. It is found out that of 11 studied chelators of bivalent cations only monosodium salt of 4-guanidino-1-hydroxybutyliden-1.1-bisphosphonic acid can efficiently renews the value of superprecipitation and ATPase activity of actomyosin in presence of lead ions. It is supposed that this renewal is underlied by binding of guanidin group of Pb ions.
