1. Functional and structural studies of the Presequence protease, PreP
Abstract : AtPreP (Arabidopsis thaliana Presequence Protease) is a zink metallooligopeptidase that is dually targeted to both mitochondria and chloroplasts. In these organelles it functions as a peptidasome that degrades the N-terminal targeting peptides that are cleaved off from the mature protein after protein import, as well as other unstructured peptides.

2. Mitochondria in Alzheimer's Disease : The Presequence Protease and Mitochondria-Associated ER Membranes
Abstract : Alzheimer’s disease (AD) is one of the most prevalent age-related neurodegenerative disorders and the accumulation of the amyloid-β peptide (Aβ) in the temporal lobe has been implicated in the pathology of AD. Synaptic transmission in neuronal cells is a highly energy dependent process, which relies on the presence and proper function of mitochondria. READ MORE

3. The mitochondrial processing peptidase-cytochrome bc₁ complex of S. oleracea
Abstract : Proteins function at distinct sites within the cell, yet most of them are encoded by the nucleus and synthesised in the cytosol. Thus, newly synthesised mitochondrial proteins have to be transported within the cell. READ MORE

4. Sorting and Import of Plant Mitochondrial Precursor Proteins
Abstract : The mitochondrial genome encodes only a handful of the mitochondrial proteins; hundreds of mitochondrial proteins are encoded in the nucleus, synthesised on cytosolic polyribosomes and subsequently imported into the organelle. Most of the proteins targeted to the mitochondria are synthesised as precursors with an N-terminal extension called presequence or targeting sequence. READ MORE

5. Studies on the structure and biogenesis of membrane proteins from the green alga Chlamydomonas reinhardtii
Abstract : The green alga unicellular Chlamydomonas reinhardtii has been used for many years as a model system in the area of photosynthesis. Therefore, the C. reinhardtii chloroplast has been the subject of many studies. In contrast, the mitochondria have received less attention. READ MORE
