Peroxisome Biogenesis: End of the Debate
The long-standing and thorny issue of the origin of peroxisomes has at last been solved. New evidence demonstrates conclusively that the peroxisomal membrane originates from the endoplasmic reticulum. This process requires the two peroxins Pex3p and Pex19p leading to intermediate structures that then mature into functionally competent organelles.
متن کاملPeroxisome biogenesis and positioning.
Plant peroxisomes are extremely dynamic, moving and undergoing changes of shape in response to metabolic and environmental signals. Matrix proteins are imported via one of two import pathways, depending on the targeting signal within the protein. Each pathway has a specific receptor but utilizes common membrane-bound translocation machinery. Current models invoke receptor recycling, which may i...
متن کاملPeroxisome biogenesis and human peroxisome-deficiency disorders
Peroxisome is a single-membrane-bounded ubiquitous organelle containing a hundred different enzymes that catalyze various metabolic pathways such as β-oxidation of very long-chain fatty acids and synthesis of plasmalogens. To investigate peroxisome biogenesis and human peroxisome biogenesis disorders (PBDs) including Zellweger syndrome, more than a dozen different complementation groups of Chin...
متن کاملPeroxisome biogenesis disorders
Defects in PEX genes impair peroxisome assembly and multiple metabolic pathways confined to this organelle, thus providing the biochemical and molecular bases of the peroxisome biogenesis disorders (PBD). PBD are divided into two types--Zellweger syndrome spectrum (ZSS) and rhizomelic chondrodysplasia punctata (RCDP). Biochemical studies performed in blood and urine are used to screen for the P...
متن کاملdiagnosis of human peroxisomal biogenesis disorders: molecular understanding of peroxisome
peroxisomes are single membrane bound organelles present in a wide variety of eukaryotes from yeast to human, have different functions, two of which are well conserved, i.e. hydrogen peroxide decomposition and fatty acid beta-oxidation. the process of peroxisome biogenesis can be divided into distinct steps including peroxisome membrane assembly, import of matrix proteins and peroxisome prolife...
