We show that oomycete-derived Nep1 (for necrosis and ethylene-inducing peptide1)-like proteins (NLPs) trigger a comprehensive immune response in Arabidopsis thaliana, comprising posttranslational activation of mitogen-activated protein kinase activity, deposition of callose, production of nitric oxide, reactive oxygen intermediates, ethylene, and the(More)
Lpx1p (systematic name: Yor084wp) is a peroxisomal protein from Saccharomyces cerevisiae with a peroxisomal targeting signal type 1 (PTS1) and a lipase motif. Using mass spectrometry, we have identified Lpx1p as present in peroxisomes, and show that Lpx1p import is dependent on the PTS1 receptor Pex5p. We provide evidence that Lpx1p is piggyback-transported(More)
We report here the identification of the Saccharomyces cerevisiae peroxisomal D,D-enoyl-CoA isomerase, an enzyme that is essential for the b-oxidation of unsaturated fatty acids. The yeast gene YLR284C was identified in an in silico screen for genes that contain an oleate response element, a transcription factor-binding site common to most fatty(More)
