A method is proposed in this paper for the determination of oxygen-18 labeled phosphate so that positional isotope experiments using sensitive and rapid liquid chromatography–QTOF–mass spectrometry (LC-QTOF-MS) experiments can be carried out. The positional isotope exchange technique is a useful tool in understanding the mechanisms and kinetics of many enzyme-catalyzed reactions. Detection of the positions and concentration of these exchanged isotopes is the key. Gas chromatography–mass spectrometry (GC-MS) and nuclear magnetic resonance imaging are commonly used analytical techniques for measurement of 18O/16O, 31P and 15N isotope enrichment. Since these techniques either require a time-consuming derivatization …

Inborn errors of metabolism (IEM) represent a group of inherited diseases in which genetic defect leads to the block on a metabolic pathway, resulting in a single enzyme dysfunction. As a downstream consequence of the residual or full loss of the enzymatic activity, there is an accumulation of toxic metabolites in the proximity of the metabolic block and/or a deficiency of an essential metabolic product which leads to the clinical presentation of the disease. While individually IEMs are rare, a collectively estimated incidence of metabolic inherited disorders is 1:800. The genetic basis of IEMs can involve abnormalities such as point …

Ribosomal protein L13a plays an extra-ribosomal function in translational silencing of GAIT (IFN-gamma-activated inhibitor of translation) element bearing mRNAs encoding inflammatory proteins but the underlying molecular mechanism of translational silencing and ribosomal incorporation of L13a remains poorly understood. Also, our laboratory showed that L13a acts as a physiological defense against uncontrolled inflammation in macrophage-specific knockout (KO) mice. However, the consequence of a total knockout of L13a in mammals remains unexplored. Therefore, our current study is focused on (i) identifying the amino acid residue(s) of L13a essential for incorporation and translational silencing of target mRNAs and (ii) studying the consequences of …
