Application

Aconitase may be usefull in diabetes research as well as to study structural conservation between iron-responsive element binding proteins (IRE-BP) and isomerases .

Actions biochimiques/physiologiques

Aconitase catalyses the stereo-specific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle. Aconitase is inhibited by cyanide, sulfide and copper and mercury at low concentrations. It is competitively inhibited by trans-aconitate. Aconitase contains an internal Fe-S cluster which is responsible for its activity.

Définition de l'unité

One unit will convert 1.0 μmole of citrate (via cis-aconitate) to isocitrate per min at pH 7.4 at 25 °C.

Superoxide (O(2)(·-)) is the proximal mitochondrial reactive oxygen species underlying pathology and redox signaling. This central role prioritizes development of a mitochondria-targeted reagent selective for controlling O(2)(·-). We have conjugated a mitochondria-targeting triphenylphosphonium (TPP) cation to a O(2)(·-)-selective pentaaza macrocyclic

Triple-negative breast cancer (TNBC) is an invasive subtype of breast cancer but paradoxically associated with increased tumor-infiltrating leukocytes. The molecular and cellular mechanisms underlying TNBC immunobiology are incompletely understood. Interleukin (IL)-17A is a pro-inflammatory cytokine that has both pro- and

Biosynthesis of iron-sulphur (Fe-S) proteins is catalysed by multi-protein systems, ISC and SUF. However, 'non-ISC, non-SUF' Fe-S biosynthesis factors have been described, both in prokaryotes and eukaryotes. Here we report in vitro and in vivo investigations of such a 'non-ISC
