Free fatty acids regulate the uncoupling protein and alternative oxidase activities in plant mitochondria. [PDF]

open access: yes, 1998
peer reviewedTwo energy-dissipating systems, an alternative oxidase and an uncoupling protein, are known to exist in plant mitochondria. In tomato fruit mitochondria linoleic acid, a substrate for the uncoupling protein, inhibited the alternative oxidase-

A discrete role for alternative oxidase under hypoxia to increase nitric oxide and drive energy production☆

open access: yesFree Radical Biology & Medicine, 2018
&NA; Alternative oxidase (AOX) is an integral part of the mitochondrial electron transport and can prevent reactive oxygen species (ROS) and nitric oxide (NO) production under non‐stressed, normoxic conditions.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

open access: yesFEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Photosynthesis, respiration and antioxidant enzymes in pepper leaves under drought and heat stresses

open access: yesBiologia Plantarum, 2010
Leaf gas exchange, chlorophyll fluorescence and activities of antioxidant enzymes were studied in two pepper (Capsicum annuum L.) cultivars grown under drought (D) and heat (H), as well as under drought and heat in combination (HD).

Cloning of an Additional cDNA for the Alternative Oxidase in Tobacco [PDF]

open access: yesPlant Physiology, 1995
The alternative oxidase is a cyanide-insensitive terminal oxidase found in a variety of organisms although it is best characterized in plants. It branches from the Cyt chain at the level of ubiquinone and does not pump protons and is thus non-energy-conserving. In thermogenic floral appendages it plays a clear role in the volatilization of compounds to

The multiple alternative oxidase proteins of soybean

open access: yes, 2015
The identity of the multiple alternative oxidase bands detected in various soybean tissues was investigated to determine if any modification that can alter the mobility on SDS-PAGE of the alternative oxidase occurs after mitochondrial import other than ...

Adapting High-Resolution Respirometry to Glucose-Limited Steady State Mycelium of the Filamentous Fungus Penicillium ochrochloron: Method Development and Standardisation.

open access: yesPLoS ONE, 2016
Fungal electron transport systems (ETS) are branched, involving alternative NADH dehydrogenases and an alternative terminal oxidase. These alternative respiratory enzymes were reported to play a role in pathogenesis, production of antibiotics and ...
