Hair bundles of the inner ear, consisting of finger-link apical cell surface protrusions, also known as stereocilia, have a specialized structure and protein composition that underlies their sensitivity to mechanical stimulation. Using mass spectrometry, identified and quantified >1,100 proteins, present from a few to 400,000 copies per stereocilium, from purified chick bundles; 336 of these were significantly enriched in bundles. Bundle proteins that we detected have been shown to regulate cytoskeleton structure and dynamics, energy metabolism, phospholipid synthesis and cell signaling. Three-dimensional imaging using electron tomography allowed us to count the number of actin-actin cross-linkers and actin-membrane connectors; these values compared well to those obtained from mass spectrometry. Network analysis revealed several hub proteins, including RDX (radixin) and SLC9A3R2 (NHERF2), which interact with many bundle proteins and may perform functions essential for bundle structure and function. The quantitative mass spectrometry of bundle proteins reported here establishes a framework for future characterization of dynamic processes that shape bundle structure and function.

ATPis formed as it is needed, primarily by oxidative processes inthe mitochondria.

ATP synthesis uses enzymes.
Energy Metabolism and Mitochondria Date through this protein complex drives a “rotor” that promotes the synthesis.
Start studying The Electron Transport Chain and Oxidative Phosphorylation.

These hydrogens form molecules of NADH and FADH that, in mitochondria, are then used to make ATP.

that inhibits the ATP/ADP transport protein in the inner binds to ADP + Pi and catalyzes the synthesis of ATP as a result.
for the molecular mechanism of ATP synthesis.

For the ATP that is charged in the mitochondria, ATP-synthase is located in the inner membrane.

When Too Much ATP Is Bad for Protein Synthesis

A second intracellular reaction can also release energy during periods of high demand. The represents another enzyme-mediated reaction for immediate ATP production by joining two molecules of ADP to form one molecule of ATP and AMP as shown in Equation 3. This reaction is less common in muscle, unless other sources of energy are lacking.

exogenous protein factors and energy in the form of ATP and GTP

The maintenance of a limited intramuscular supply of ATP and the production of AMP, Pi and ADP mediated by phosphocreatine and adenylate kinase as mentioned above, rapidly stimulates the breakdown of macronutrients to resynthesize ATP at a rate equivalent to ATP’s rate of use and intensity of physical activity. While ATP hydrolysis occurs anaerobically enabling rapid energy transfer during strenuous short-lived physical activity; the resynthesis of ATP can be aerobic or anaerobic in the case of glucose metabolism or exclusively aerobic for lipid and protein metabolism.

Sep 11, 2006 · Does protein synthesis use ATP

Most of the energy for ATP generation derives from the aerobic phosphorylation/oxidation pathway, that is, the oxidation of carbohydrate, lipid and protein macronutrients as oxygen is reduced. Figure 1 depicts the oxidative pathways of carbohydrate, fat and protein macronutrients in ATP generation.

The main protein synthesis steps are: protein synthesis ..

Oxidative phosphorylation.
of ATP The overall equation for ATP hydrolysis is usually written: ATP + H 2 O = ADP + inorganic phosphate (Pi) reactions of ATP hydrolysis or synthesis.
The ATP synthase: the understood, the uncertain and the mechanism that leads to the chemical synthesis of ATP from ADP and Pi.

Protein synthesis and ATP Flashcards | Quizlet

Adenosine triphosphate (ATP) is the primary energy "currency" in most living organisms. Storing readily-available energy in the form of a chemical bond, ATP delivers it to a reaction site and releases it in the process of hydrolysis, providing an energy supply for enzymatic reactions and biomechanical processes. ATP synthase is a large (about 100,000 atoms) protein, which includes a transmembrane F0 unit coupled to a solvent-exposed F1 unit via a central stalk gamma. The F0 unit utilizes a transmembrane electrochemical potential (proton motive force), converting it into the mechanical energy of the stalk rotation. The rotation leads to cyclic conformational changes in the catalytic sites in the F1 unit, thereby driving ATP synthesis. ATP synthase can also function in the reverse direction, hydrolyzing ATP and utilizing the released energy to pump protons across the membrane. This reversibility, along with the nearly 100% efficiency and the recently discovered, remarkably symmetric structure (1997 Nobel Prize in Chemistry), makes ATP synthase a perfect system for exploring interconversion between mechanical and electrochemical energy in molecular motors.
