1. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes
Abstract : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. READ MORE

2. Studies of the thioredoxin system in redox signaling and oxidative stress
Abstract : Reactive oxygen species exert reversible posttranslational modifications in proteins containing redox sensitive thiols, thereby affecting several cellular processes and protein functions. Reductive enzyme systems, such as the thioredoxin system, can reverse most of these cysteine modifications. READ MORE

3. The chloroplast lumen : New insights into thiol redox regulation and functions of lumenal proteins
Abstract : In higher plants oxygenic photosynthesis primarily takes place in the chloroplasts of leaves. Within the chloroplasts is an intricate membrane system, the thylakoid membrane, which is the site of light harvesting and photosynthetic electron transport. READ MORE

4. Proteomic analysis of Arabidopsis thaliana
Abstract : A complete proteome analysis of the chloroplast stroma, using 2D-PAGE, from spinach and Arabidopsis was performed. To improve the identification of proteins a computer program named SPECLUST was used. READ MORE

5. PTPs : redox controlled regulators of cell signaling and transformation
Abstract : Protein tyrosine phosphatases (PTPs) are important redox regulated enzymes that control the tyrosine phosphorylation status in the cell. These studies aimed to increase the understanding on how PTPs are controlled by reversible oxidation in different pathological settings such as hypoxia and restenosis and to which extent oxidized PTPs contribute to certain diseases.
