Sentences with phrase «electron transport proteins»

But when you have excessive iron, it catalyzes the formation of excessive hydroxyl free radicals from the peroxide, which decimate your mitochondrial DNA, mitochondrial electron transport proteins and cellular membranes.

With the images produced by ECT, the team was the first to see how electron transport proteins were distributed in the membrane to form the nanowires.

Not exact matches

But in 2013, a research scientist in El - Naggar's laboratory, Sahand Pirbadian, discovered that these projections, referred to as «nanowires,» were actually extensions of the cell membrane covered in cytochromes — proteins containing iron that facilitate electron transport.

These 10 sets encode proteins responsible for four related bioenergetic processes: nuclear - encoded mitochondrial electron transport (the key energy - extracting operation), mitochondrial biogenesis (by which new mitochondria are formed) as well as glucose utilization and glucose sensing (processes by which glucose levels are evaluated and modified).

These include more sensitive mass spectrometry for detecting, identifying and quantifying protein molecules, electron microscopy for visualizing an assortment of components of the nano - machine that transports toxins, and fluorescence confocal microscopy, which can label proteins with light emitting dyes.

Columbia researchers have uncovered new roles for proteins of the electron transport chain that implicate them in utilization of phenazines.

They found that the electron transport chain so critical to the conversion of electrons to energy can and is operating deep down in the oxygen - deprived biofilm and that in these environments, the bacterium depends on a specific part of the chain's terminal oxidase — a protein called CcoN4 — to access oxygen and grow normally.

Nielsen believes the secret is a bacterial pulley system of sorts: Oxygen - processing bacteria at the top connect to digestive microbes below via long protein threads that transport electrons.

The mutations that underlie the mitochondriopathies Myoclonic Epilepsy with Ragged Red Fibers (MERRF) and some variants of Mitochondrial Encephalomyopathy, Lactic Acidosis, and Strokelike Episodes (MELAS) create defective versions of particular mitochondrial amino acid tRNAs, leading to inefficient translation of electron transport system (ETS) subunit proteins.

This protein is one of the nuclear - coded polypeptide chains of cytochrome c oxidase, the terminal oxidase in mitochondrial electron transport.

This research can lead to a better understanding of how these proteins work in other electron transport chain mechanisms, which could alter how we view this entire process.»

Cytochromes are electron - transporting protein pigments concerned with cell respiration that contain an iron - containing molecule called heme, allied to that of hemoglobin.

Your body's electron transport system, as part of iron / sulfur proteins in mitochondria, the energy factories of your cells
