Reactive oxygen species (ROS) are at once unsought by-products of metabolism and critical regulators of multiple intracellular signaling cascades. In nonphotosynthetic eukaryotic cells, mitochondria are well-investigated major sites of ROS generation and related signal initiation. Peroxisomes are also capable of ROS generation, but their contribution to cellular oxidation-reduction (redox) bala...
Translation of mRNA into a polypeptide chain is a highly accurate process. Many prokaryotic and eukaryotic viruses, however, use leaky termination of translation to optimize their coding capacity. Although growing evidence indicates the occurrence of ribosomal readthrough also in higher organisms, a biological function for the resulting extended proteins has been elucidated only in very few cas...
Using a new screening procedure for the isolation of peroxisomal import mutants in Pichia pastoris, we have isolated a mutant (pex7) that is specifically disturbed in the peroxisomal import of proteins containing a peroxisomal targeting signal type II (PTS2). Like its Saccharomyces cerevisiae homologue, PpPex7p interacted with the PTS2 in the two-hybrid system, suggesting that Pex7p functions a...
To identify unknown proteins from plant peroxisomes, the Arabidopsis genome was screened for proteins with putative major or minor peroxisome targeting signals type 1 or 2 (PTS1 or PTS2), as defined previously (Reumann S [2004] Plant Physiol 135: 783-800). About 220 and 60 proteins were identified that carry a putative PTS1 or PTS2, respectively. To further support postulated targeting to perox...
