ROS/RNS by alpha/ Beta oxidation of branched and very long chain fatty acids

peroxisomal membrane via PXMP2 known only (89). Even mechanism of transfer of
end products of peroxisomal metabolism to mitochondria and Endoplasmic reticulum
is unexplored (88). Although two reports have shown that PEX11 is involved in
peroxisomes-mitochondria association and its interaction with ERMES complex
(90,91).

Peroxisomal evolution suggests discriminatory
gain of enzymes and even re-targeting 
complete pathways to peroxisomes as suggested for Glyoxylate
aminotransferase in accordance with dietary habbits (Birdsey et al. 2004); glycolysis and purine salvage pathways in
glycosomes (Michels et al. 2006); re-targeting of proteins of different sources to
the peroxisomes have been reported elsewhere (Gabaldón et al. 2006). Peroxisome is considered as
product of evolutionary fiddling, harbouring flexible proteome which gets
shaped in due course of evolution to adapt to specific needs of every lineage
(29)

 

Peroxisomal
protein Evolution:

 

An average mammalian cell may harbour up to
thousands of peroxisomal number starting from 0.2um to 1um diameter.  Peroxisomal biogenesis is reported to occur
from budding of endoplasmic reticulum (14). Experiments performed in response to above
hypothesis proved that peroxisomal membrane and matrix proteins get synthesized
on free ribosomes and transported into peroxisomes post translationally (15). Proteins
bearing peroxisomal targeting sequences 1 and 2 along with the aid of Pex5p and
Pex7p receptors respectively target a protein from cytosol to the peroxisomal
matrix (16). Protein secretion and prevention of alkaline extracellular
proteases from Endoplasmic reticulum is affected due to mutations in SEC238, SRP54, PEX1, PEX2,
PEX6 and PEX9 (17). Interconnection
between lipid and ROS metabolism require teamwork of peroxisomes along with
Mitochondria, Endoplasmic reticulum, lipid droplets and lysosomes (31).

Peroxisomes are one of pervasive organelles in eukaryotic cells,
dynamic in nature, multiutility subcellular compartment having great metabolic
potential. Peroxisomes have power of autonomous replication. They generate
Reactive oxygen species after Fatty acid Beta Oxidation. A substantial lethal group of human inborn errors may occur due to genetic defects in
peroxisomal genes prejudicing their functions leading to peroxisomal disorders
(13).
