Glyoxisome

A glyoxisome is a form of peroxisome and therefore a cell organelle . They occur in plants and molds (so-called filamentous fungi).

properties

Glyoxisomes are found in fat storage tissue of seeds . They are involved in fat loss through β-oxidation and in gluconeogenesis through the glyoxylate cycle . Glyoxisomes contain the enzymes isocitrate lyase and malate synthase , which are characteristic of the glyoxylate cycle . These and other peroxisomal proteins are imported from the cytosol via the signal sequences (target control signals) PTS1 and PTS2 .
