Bicarbonate- and hydroxylamine-dependent degradation of adenosine triphosphate.
The previous papers of this series were concerned with the role of biotin in the carboxylation step in leucine metabolism (1) and with the purification of an enzyme (referred to as carbon dioxideactivating enzyme) which catalyzes the bicarbonateand hydroxylamine-dependent degradation of adenosine triphosphate (2). The activating enzyme was assayed by calorimetric determination (3) of a nonnucle...
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 کاملAccelerated mitochondrial adenosine diphosphate/adenosine triphosphate transport improves hypertension-induced heart disease.
BACKGROUND Strong evidence suggests that mitochondrial malfunction, which leads to disturbed energy metabolism and stimulated apoptosis, is a linchpin in the induction and manifestation of cardiac failure. An adequate exchange of ATP and ADP over the inner mitochondrial membrane by the adenine nucleotide translocase (ANT) is thereby essential to guarantee the cellular energy supply. METHODS A...
متن کاملMechanism of adenosine triphosphate hydrolysis by actomyosin.
The hydrolysis of ATP by acto-HMM has been studied during the transient state using a rapid-mixing apparatus. The rate of substrate binding was slightly slower and the rate of hydrolysis of the first molecule of ATP was essentially the same as for heavy meromyosin (HMM) alone. The rate of acto-HMM dissociation after binding substrate was too fast to measure in a stopped-flow apparatus, conseque...
متن کاملAdenosine 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...
