Most plants contain two isoforms of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) activase (Rca), a chloroplast protein that maintains the activity of Rubisco during photosynthesis. The longer (α-) Rca isoform has previously been shown to regulate the activity of Rubisco in response to

To determine if ventricular cerebrospinal fluid (vCSF) alpha-tocopherol levels in Parkinson's disease (PD) patients can be increased by oral alpha-tocopherol supplementation and whether vCSF levels are linearly related to plasma alpha-tocopherol levels. In spite of its putative neuroprotective properties, alpha-tocopherol

There is evidence that increased blood concentrations of homocysteine may be a risk factor for Alzheimer's disease. (E)-4-hydroxy-2-nonenal (HNE) is a neurotoxic product of lipid peroxidation that is increased in the ventricular fluid and brains of patients with Alzheimer's disease.

Thiamine is an essential cofactor for several important enzymes involved in brain oxidative metabolism, such as the alpha-ketoglutarate dehydrogenase complex (KGDHC), pyruvate-dehydrogenase complex (PDHC), and transketolase. Some investigators reported decreased thiamine-diphosphate levels and decreased activities of KGDHC, pyruvate-dehydrogenase complex and

Members of the 14-3-3 protein family interact with hundreds of different, predominantly phosphorylated, proteins. 14-3-3 dimers are prevalent but exist at the equilibrium with the monomers. Our previous studies using the engineered monomeric 14-3-3ζ (14-3-3ζm) showed that 14-3-3ζ monomer retained

We could identify the MPTP-like compound and isoquinoline derivative N-methyl-norsalsolinol (2-MDTIQ) in cerebrospinal fluid (CSF) of patients with Parkinson's disease. The presence of 2-MDTIQ negatively correlated with the disease duration. In order to study the relationship between presence of 2-MDTIQ

Magnesium transporter subtype 1 (MagT1) is a newly discovered and evolutionarily conservative magnesium membrane transporter with channel like properties. Previous reports have demonstrated that MagT1 is important to cellular magnesium homeostasis. In this study, we investigated whether drosophila MagT1 (dMagT1)

γ-Glutamyltranspeptidases (γ-GTs) cleave the γ-glutamyl amide bond of glutathione and transfer the released γ-glutamyl group to water (hydrolysis) or acceptor amino acids (transpeptidation). These ubiquitous enzymes play a key role in the biosynthesis and degradation of glutathione, and in xenobiotic
