Peroxisomes

MOLECULAR CELL BIOLOGY: ESSAY OUTLINE

- 1 - MOLECULAR CELL BIOLOGY: ESSAY OUTLINE What are peroxisomes? What do they do? And, how are proteins targeted to them? Are they related to the ER/Golgi?

Cells and DNA (excerpt)

Lysosomes and peroxisomes (illustration on page 6) These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle

Uric acid degrading enzymes, urate oxidase and allantoinase ...

In the rat, and in most other mammals that display urate oxidase activity and metabolize uric acid to allantoin, this enzyme is associated specifically with the crystalloid core present within the peroxisomes in hepatic parenchymal cells (De Duve and Baudhuin, 1966; Shnitka, 1966; Tsukada et al., 1966 ...

•These complexes contrast with the linear arrays of cellulose-producing proteins in noncharophycean algae. 13 •A second ultrastructural feature that unites charophyceans and land plants is the presence of peroxisomes.

Furthermore, additional features of the constitutive presence of peroxisomes are demonstrated. 562 DOG-resistant colonies were tested, 24 of them demonstrating constitutive A OX formation.

PPARs are the nuclear receptors responsible for the effects of ligands, collectively known as peroxisomeproliferators, that alter both the number and size of peroxisomes [19] .
