When stoichiometric amounts of tropomyosin (TM) are bound to F-actin in the presence of 2 mM ATP, the MG2+-activated acto-heavy meromyosin (HMM) ATPase is inhibited by about 60% in 5 mM MgCl2-30 mM KCl. If the concentration of MgCl2 is reduced to 1 m

The full amino acid composition of bovine prothrombin has been measured by using ion-exchange chromatography. In addition, other methods were used for the estimation of tyrosine, tryptophan, phenylalanine, and amide ammonia. Cysteine-cystine were est

An ultracentrifugal study has been made on myosin treated with methylmercuric hydroxide. 1. 1. Myosin is transformed by tritration of its -SH groups with methylmerucuric hydroxide to a faster-sedimenting product. This occurs in the same range of meth

1. 1. Treatment with 0.1 M Na 2 CO 3 releases from myosin a protein of about 29,000 molecular weight, which seems to be closely related to the material released from myosin by concentrated urea. 2. 2. The amino acid composition is presented. A relati

Treatment with heavy-metal cyanides at alkaline pH splits both rabbit and crayfish myosins into three portions. The fraction salting out at 38–42% ammonium sulfate saturation has a sedimentation rate of about 3 S . The amino acid compositions of th

1. 1. Purified tropomyosin has been prepared from adult and larval stages of the blowfly, Phormia regina ; purified myosin and actin have been prepared from the adult stage only. Special procedures were required in the preparation of all three protei

It is confirmed that the presence of native tropomyosin is required in order for the removal of Ca ++ to cause inhibition of the Mg ++ -activated ATPase of actomyosin and acto-heavy-meromyosin. Native tropomyosin is present in routinely purified samp
