| Description | Peroksisome is ronde of ovale organelle met 'n fyn, granulêre matriks omring deur ’n enkelmembraan, war veral in lewer- en nierselle gevind word. Katalase-positiewe strukture of mikroperoksisome word egter in alle eukariotiese selle behalwe die volwasse rooibloedsel gevind. Ensiemproteiene (ongeveer vyftig) bestem vir peroksisome word in vry ribosome in die sitosol gesintetiseer en word in die matriks van vormende organelle geinkorporeer deur middel van twee sinjaalpeptiede, 'n karboksiterminale SKL-tripeptied en 'n moontlike aminoterminale undekapeptied. Die funksies van peroksisome behels, onder andere, ekstramitochondriale ß-oksidasie (veral van baie langkettingvetsure), sintese van plasmalogene en ander eterlipiede en metabolisme van waterstofperoksied. Peroxisomes are round or oval organelles with a finely granular matrix surrounded by a single membrane and are especially found in liver and kidney cells. Catalase-positive structures or microperoxisomes are, however, found in all eucaryotic cells except mature red blood cells. Enzyme proteins (approximately fifty) destined for peroxisomes are synthesized in free cytosolic ribosomes and are incorporated in the matrix of forming organelles with the aid of two signal peptides: a carboxy terminal SKL-tripeptide and possibly an aminoterminal undecapeptide. The functions of peroxisomes include, inter alia, extramitochondrial fi-oxidation (especially very long chain fatty acids), synthesis of plasmalogens and other ether lipids and metabolism of hydrogen peroxide. | |
