Origine peroxysome
WitrynaPeroxisomes are small membrane-bound organisms found within the cytoplasm of eukaryotic cells. The primary function of peroxisomes is to oxidize certain biomolecules, although peroxisomes have other functions as well, such as enabling the synthesis of plasmalogens (a type of membrane lipid). Peroxisomes also have an additional set of … Witryna13 mar 2024 · ↳ 1) L'atomistique ...

WitrynaPeroxisomes play a central role in metabolism as exemplified by the fact that many genetic disorders in humans have been identified through the years in which there is an impairment in one or more of these peroxisomal functions, in most cases associated with severe clinical signs and symptoms. WitrynaPeroxisome biogenesis conceptually consists of the (a) formation of the peroxisomal membrane, (b) import of proteins into the peroxisomal matrix and (c) proliferation of the organelles. Combined genetic and biochemical approaches led to the identification of 25 PEX genes-encoding proteins required for the biogenesis of peroxisomes, so-called ...
