Abstract
A variety of metabolic pathways are sequestered within peroxisomes. Thus, the participating enzymes and the metabolic substrates have to be imported into this organelle. The mechanisms mediating an efficient and specific transport of soluble and membrane proteins to peroxisomes are a major focus of interest. The transfer of small organic compounds across the peroxisomal membrane by specific transporter proteins and the metabolic interconversion of these compounds within peroxisomes are the second major focus. Both aspects are of medical importance, because a dysfunction in transport processes has been linked to human diseases such as X-linked adrenoleukodystrophy, Alzheimers disease or metabolic disorders.
