diagnosis 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...
متن کاملPeroxisomal disorders I: biochemistry and genetics of peroxisome biogenesis disorders.
The peroxisomal disorders represent a group of genetic diseases in humans in which there is an impairment in one or more peroxisomal functions. The peroxisomal disorders are usually subdivided into two subgroups including (i) the peroxisome biogenesis disorders (PBDs) and (ii) the single peroxisomal (enzyme-) protein deficiencies. The PBD group is comprised of four different disorders including...
متن کاملPeroxisome assembly: matrix and membrane protein biogenesis
The biogenesis of peroxisomal matrix and membrane proteins is substantially different from the biogenesis of proteins of other subcellular compartments, such as mitochondria and chloroplasts, that are of endosymbiotic origin. Proteins are targeted to the peroxisome matrix through interactions between specific targeting sequences and receptor proteins, followed by protein translocation across th...
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 کاملThe peroxin pex3p initiates membrane assembly in peroxisome biogenesis.
Rat cDNA encoding a 372-amino-acid peroxin was isolated, primarily by functional complementation screening, using a peroxisome-deficient Chinese hamster ovary cell mutant, ZPG208, of complementation group 17. The deduced primary sequence showed approximately 25% amino acid identity with the yeast Pex3p, thereby we termed this cDNA rat PEX3 (RnPEX3). Human and Chinese hamster Pex3p showed 96 and...
