Adenosine triphosphate inhibition in myosin adenosine triphosphate systems.
Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the nucleoside triphosphatase activity of myosin A could be qual...
متن کاملInhibition by Adenosine 5'-Triphosphate
Two major species of glucose-6-phosphate dehydrogenase (EC 1.1.1.49) differing in size, pyridine nucleotide specificity, and susceptibility to inhibition by adenosine 5'-triphosphate (ATP) were detected in extracts of Pseudomonas multivorans (which has recently been shown to be synonymous with the species Pseudomonas cepacia) ATCC 17616. The large species (molecular weight ca. 230,000) was acti...
متن کاملHydrolysis of Adenosine Triphosphate by Crystalline Yeast Pyrophosphatase
Schlesinger and Coon's report that crystalline yeast inorganic pyrophosphatase, in addition to its known ability to hydrolyze inorganic pyrophosphate in the presence of Mg ions, is also able to catalyze the hydrolysis of ATP and ADP in the presence of Zn ions was confirmed. A systematic study showed that the ratio of 370 of PPase-Mg over ATPase-Zn activities per milligram protein in various pre...
متن کاملInhibition of glucose 6-phosphate dehydrogenase by adenosine 5'-triphosphate.
D-glucose 6-phosphate dehydrogenase (G6PDH) catalyzes the oxidation of glucose 6-phosphate (G6P) to 6-phosphogluconate-6-lactone and thereby constitutes the step which introduces hexoses into the "pentose cycle" pathway. This well-known enzyme, which is widely distributed in nature, was purified to varying degrees from different sources (for literature see refs. 1 and 2). The yeast enzyme,3 4 w...
متن کاملPurification and Properties of Bakers' Yeast Trehalase.
Since recent surveys of insect hemolymph (1, 2) have shown that trehalose is the major blood sugar, the hydrolytic enzyme trehalase has also awakened the interest of investigators. A purified preparation of the enzyme from Galleria mellonella (3) and from Phormia regina (4) was recently obtained and some of its properties described. The biosynthesis of trehalose with an enzyme preparation from ...
