Abstract:
Peroxisome organelles have a versatile metabolism whose enzymatic content can be modulated by physiological and environment-dependent cellular conditions. They are characterized by a highly active nitro-oxidative metabolism and basic elements (H2O2 and nitric oxide (NO)) with signaling properties. However, new elements have increased our understanding of the connections between peroxisomes and other cellular compartments. Furthermore, the presence of calcium (Ca2+) intensifies communication between different signaling molecules and the relationship of Ca2+ itself with NO and H2O2.

Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
