glyoxysome

a type of organelle (microbody) containing ENZYMES of the GLYOXYLATE CYCLE. It is found in plants, particularly in germinating seeds.

glyoxysomes: Subcellular microbody present in the cytoplasm of many oil seeds; enzymes packaged in the glyoxysome convert lipids to carbohydrates during the germination process.
CuZnSOD is located in the mitochondria (Duke and Salin, 1985) and glyoxysomes (Sandalio and Del Rio, 1987), detoxifies superoxide radicals occurring from photosynthetic activities and physiological stress responses.
APX is found in the different cellular compartments such as stroma and thylakoid, microbody including glyoxysomes and peroxisomes, cytosol and mitochondria.
These metabolites are normal products of natural redox reactions in mitochondrial respiratory and photosynthetic electron transport chains, peroxisomes and glyoxysomes.
The fatty acid degradation involves P-oxidation in glyoxysomes, glyoxylate cycle, Krebs cycle, part of gluconeogenesis and glycolysis, the pyruvate decarboxylation and again Krebs cycle (Figure 1).
In addition, peroxisomes and glyoxysomes, collectively referred to as micro bodies, are sub-cellular organelles that do not have an energy-coupled electron transport system, but instead contain flavine oxidases, which catalyse the substrate-dependent reduction of oxygen to [H.
Lipids can also serve as a source for the formation of membrane systems, such as those of the glyoxysomes, which require non polar lipids and phospholipids for their enlargement during seed germination (Chapman and Trelease, 1991).
2] in the cells, peroxisomes and glyoxysomes also contain SOD and APX, which are responsible for its production and scavenging [16].
