Making ATP.
We present a mesoscopic model for ATP synthesis by F(1)F(o) ATPase. The model combines the existing experimental knowledge of the F(1) enzyme into a consistent mathematical model that illuminates how the stages in synthesis are related to the protein structure. For example, the model illuminates how specific interactions between the gamma, epsilon, and alpha(3)beta(3) subunits couple the F(o) m...
متن کاملSequencing and Molecular Analysis of ATP 6 and ATP 8 of Mitochondrial Genome in Khorasanian Native Chickens
In order to perform breeding programs and improve production of native chickens, preserving genetic diversity in different areas of Iran is important due to the reduced available population. Genome sequencing is considered the most functional approach to determine the phylogeny relation between close populations. The aim of the present study was the evaluation of the phylogeny and genetic nucle...
متن کاملATP synthase
All living species use ATP as a general source of energy by hydrolysing it into ADP and phosphate. In most species the regeneration of this vital molecule is catalysed by the H+-transporting F1F0 ATP synthases, marvellous machines that couple the flow of protons down an electrochemical gradient to form ATP from ADP and phosphate. Under certain circumstances these enzymes can also work in the re...
متن کاملATP modulation of ATP-sensitive potassium channel ATP sensitivity varies with the type of SUR subunit.
ATP-sensitive potassium (K(ATP)) channels comprise Kir and SUR subunits. Using recombinant K(ATP) channels expressed in Xenopus oocytes, we observed that MgATP (100 microm) block of Kir6.2/SUR2A currents gradually declined with time, whereas inhibition of Kir6.2/SUR1 or Kir6.2DeltaC36 currents did not change. The decline in Kir6.2/SUR2A ATP sensitivity was not observed in Mg(2+) free solution a...
متن کاملA soluble mitochondrial ATP synthetase complex catalyzing ATP-phosphate and ATP-ADP exchange.
The highly purified soluble ATP synthetase complex from mitochondria, containing energy-transfer Factor A (the terminal ADP phosphorylation enzyme of oxidative phosphorylation) and Factor D, catalyzes ATP-P(i) and ATP-ADP exchange reactions. The ATP-P(i) exchange activity is inhibited by low concentrations of the uncouplers of oxidative phosphorylation, oligomycin and p-chloromercnriphenylsulfo...
