Studies on Myofibrillar Adenosine Triphosphatase with Calcium-free Adenosine Triphosphate.
It has been reported by several groups of workers that incubation of the relaxing factor granar of muscle with magnesium and adenosine triphosphate results in the formation of a soluble relaxing substance capable of inhibiting the magnesium-activated adenosine triphosphatase activity of myofibrils or actomyosin (3-6) and the contraction of single glycerinated muscle fibers (7). In addition, Uri...

متن کاملStudies on cardiac myofibrillar adenosine triphosphatase.
It has long been known that myosin and actin can be obtained from heart as well as from skeletal muscle and that, in combining them to form actomyosin, they are interchangeable with their skeletal counterparts (1). The contractile properties of glycerolextracted cardiac strips and cardiac actomyosin (myosin B) threads and bands have also been demonstrated (2, 3). The molecular parameters of car...
متن کاملStudies on Adenosine Triphosphate Transphosphorylases
The isolation of the crystalline enzymes, adenosine triphosphate-creatine transphosphorylase (1) and adenosine triphosphate-adenosine 5’-phosphate transphosphorylase (2), made possible a comparative approach to the general problem of the mechanism of action of the adenosine triphosphate transphosphorylases. The present series of papers extends earlier studies from this laboratory on these enzym...
متن کاملSynthesis of adenosine triphosphate and exchange between inorganic phosphate and adenosine triphosphate in sodium and potassium ion transport adenosine triphosphatase.
Radioactive adenosine triphosphate was synthesized transiently from adenosine diphosphate and radioactive inorganic phosphate by sodium and potassium adenosine triphosphatase from guinea pig kidney. In a first step, K+-sensitive phosphoenzyme was formed from radioactive inorganic phosphate in the presence of magnesium ion and 16 mM sodium ion. In a second step the addition to the phosphoenzyme ...
