Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Malate dehydrogenase activity in human seminal plasma and spermatozoa homogenates

Çukurova Üniversitesi Tıp Fakültesi Dergisi, 2013
Purpose: Malate Dehydrogenase is an important enzyme of the Krebs cycle, most cells require this enzyme for their metabolic activity. We evaluated the Malate Dehydrogenase (NAD/NADP) activity in human seminal plasma and sperm homogenates in ...

Gain of interaction of ALS-linked G93A superoxide dismutase with cytosolic malate dehydrogenase

Neurobiology of Disease, 2008
Protein interactions of the Amyotrophic Lateral Sclerosis (ALS)-linked copper–zinc superoxide dismutase (hSOD1) G93A mutation were studied using a fluorescence resonance energy transfer (FRET) based screening system.

Proteomic Profiling of Primary Hippocampal Neurons Reveals Noncanonical GFAP Expression and Metabolic Adaptations in Glia‐Free Culture

PROTEOMICS, EarlyView.
ABSTRACT Despite their widespread use as a research model, a comprehensive, quantitative proteomic profile of the cultured hippocampal neurons has remained unexplored. Here, we provide the first global proteomic characterization of primary murine hippocampal neurons cultured for 14 days under near‐physiological glucose conditions (2.5 mM).

Effect of Caffeine on the Expression Pattern of Water-Soluble Proteins in Rice () Seedlings

Natural Product Communications, 2015
It has been suggested that caffeine acts as an allelochemical which influences the germination and growth of plants. The effect of caffeine on the expression profiles of proteins was investigated in shoot-root axes of rice (Oryza sativa) seedlings.

An experimental point of view on hydration/solvation in halophilic proteins

Frontiers in Microbiology, 2014
Protein-solvent interactions govern the behaviour of proteins isolated from extreme halophiles. In this work, we compared the solvent envelopes of two orthologous tetrameric malate dehydrogenases from halophilic and non-halophilic bacteria.

Branched‐Chain Amino and Keto Acids Reduce Hepatocyte Lipid Droplet Size and Number via Distinct Proteomic Pathways

PROTEOMICS, EarlyView.
ABSTRACT Branched‐chain amino acids (BCAA) and their corresponding keto acids (BCKA) have been associated with changes in hepatic lipid metabolism and the resulting alterations in intracellular triglyceride concentrations. In this study, we utilized a previously established hepatocyte model to investigate the impact of BCAA and BCKA supplementation on ...

Role of NAD+-Dependent Malate Dehydrogenase in the Metabolism of Methylomicrobium alcaliphilum 20Z and Methylosinus trichosporium OB3b

Microorganisms, 2015
We have expressed the l-malate dehydrogenase (MDH) genes from aerobic methanotrophs Methylomicrobium alcaliphilum 20Z and Methylosinus trichosporium OB3b as his-tagged proteins in Escherichia coli.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

A universal metabolite repair enzyme removes a strong inhibitor of the TCA cycle

Nature Communications
A prevalent side-reaction of succinate dehydrogenase oxidizes malate to enol-oxaloacetate (OAA), a metabolically inactive form of OAA that is a strong inhibitor of succinate dehydrogenase. We purified from cow heart mitochondria an enzyme (OAT1) with OAA
