Peroxisome biogenesis: the peroxisomal endomembrane system …

WebJul 15, 2009 · Characteristic of peroxisomes is the presence of hydrogen-peroxide-producing oxidases (hence the name peroxisome) and catalase, which breaks down the hydrogen peroxide. The importance of the peroxisome for human health is emphasised by the existence of inherited disorders that are caused by peroxisomal dysfunction ( … A peroxisome (IPA: [pɛɜˈɹɒksɪˌsoʊm]) is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells. Peroxisomes are oxidative organelles. Frequently, molecular oxygen serves as a co-substrate, from which hydrogen peroxide (H2O2) is then formed. Peroxisomes … See more Peroxisomes (microbodies) were first described by a Swedish doctoral student, J. Rhodin in 1954. They were identified as organelles by the Belgian cytologist Christian de Duve in 1967. De Duve and co-workers discovered … See more Peroxisomes are small (0.1–1 µm diameter) subcellular compartments (organelles) with a fine, granular matrix and surrounded by a single biomembrane which are located in … See more Peroxisomes can be derived from the smooth endoplasmic reticulum under certain experimental conditions and replicate by membrane growth and division out of pre … See more PEX genes encode the protein machinery ("peroxins") required for proper peroxisome assembly, as described above. Membrane assembly and maintenance requires three of these (peroxins 3, 16, and 19) and may occur without the import … See more A major function of the peroxisome is the breakdown of very long chain fatty acids through beta oxidation. In animal cells, the long fatty acids are … See more The diverse functions of peroxisomes require dynamic interactions and cooperation with many organelles involved in cellular lipid … See more Peroxisomal disorders are a class of medical conditions that typically affect the human nervous system as well as many other organ systems.
