Metabolic Network Control of Oxidative Phosphorylation

It is demonstrated that Pi signaling results in the balanced modulation of oxidative phosphorylation, by influencing both ΔGH+ generation and ATP production, which may contribute to the energy metabolism homeostasis observed in intact systems. Expand
Distribution of mitochondrial NADH fluorescence lifetimes: steady-state kinetics of matrix NADH interactions.
In both preparations, the rate of NADh oxidation was proportional to the amount of NADH in the long lifetime pools, suggesting that a significant fraction of the bound NADH might be associated with oxidative phosphorylation, potentially in complex 1. Expand
Importance of specific native lipids in controlling the photocycle of bacteriorhodopsin.

It is shown here that full restoration can also be obtained with combinations of squalene (SQ) and phosphatidyl glycerophosphate (PGP) which act synergistically. Expand
Role of calcium in metabolic signaling between cardiac sarcoplasmic reticulum and mitochondria in vitro.

It is suggested that this balanced activation by cytosolic Ca(2+) is partially responsible for the minimal alteration in energy metabolism intermediates that occurs with changes in cardiac workload in vivo. Expand
Effects of methyl parathion on the growth, cell size, pigment and protein content of Chlorella protothecoides
The results suggest multiple sites of action of the insecticide on cell metabolism, including inhibition of cell division, as well as chlorophyll content, which was inhibited more than any other parameter measured. Expand
NMR MEASUREMENT OF DIPOLAR COUPLINGS IN PROTEINS ALIGNED BY TRANSIENT BINDING TO PURPLE MEMBRANE FRAGMENTS
One-bond internuclear dipolar couplings in molecules that are aligned relative to an external magnetic field constrain the orientations of the corresponding vectors relative to the molecule’s… Expand
Control of the integral membrane proton pump, bacteriorhodopsin, by purple membrane lipids of Halobacterium halobium.
This paper defines conditions which are important in the reconstitution procedure, using a group of quantitative parameters which measure the extents of damage and repair. Expand
Chemical and functional studies on the importance of purple membrane lipids in bacteriorhodopsin photocycle behavior
The BR photocycle in Triton‐treated PM can be restored to near normal behavior by reconstitution with native PM lipids, and isolated squalenes are not effective whereas PL alone partially restores normal photocyCLE characteristics. Expand
Isolation and homogeneity of mycobacillin.
Mycobacillin has been purified and isolated as fine needle-shaped crystals from culture filtrates of Bacillus subtilis and physicochemical studies indicate that the pure compound is a polypeptide, somewhat different in chemical composition from the known antifungalpolypeptides. Expand
Selective action of mycobacillin on the cellular permeability of Aspergillus niger.

- Biology, Medicine
- The Journal of antibiotics
- 1 April 1986
Cells of Aspergillus niger normally release not all but of some specific cell constituents viz., lysine, proline, ATP, Pi, Na+, K+ and Ca2+ in the absence of mycobacillin. Mycobacillin enhances the… Expand
