Peroxisome Biogenesis: Involvement of ARF and Coatomer
Peroxisomal membrane protein (Pmp)26p (RnPex11p), a major constituent of induced rat liver peroxisomal membrane, was found to contain a COOH-terminal, cytoplasmically exposed consensus dilysine motif with the potential to bind coatomer. Biochemical as well as immunocytochemical evidence is presented showing that peroxisomes incubated with preparations of bovine brain or rat liver cytosol recrui...
متن کاملPeroxisome biogenesis: where Arf and coatomer might be involved.
The present review summarizes recent observations on binding of Arf and COPI coat to isolated rat liver peroxisomes. The general structural and functional features of both Arf and coatomer were considered along with the requirements and dependencies of peroxisomal Arf and coatomer recruitment. Studies on the expression of mammalian Pex11 proteins, mainly Pex11alpha and Pex11beta, intimately rel...
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...
