Crystal structure of the protein At3g01520, a eukaryotic universal stress protein-like protein from arabidopsis thaliana in complex with AMP
Members of the universal stress protein (USP) family are conserved in a phylogenetically diverse range of prokaryotes, fungi, protists, and plants and confer abilities to respond to a wide range of environmental stresses. ...
Disparate peroxisome‐related defects in Arabidopsis pex6 and pex26 mutants link peroxisomal retrotranslocation and oil body utilization
Catabolism of fatty acids stored in oil bodies is essential for seed germination and seedling development in Arabidopsis. This fatty acid breakdown occurs in peroxisomes, organelles that sequester oxidative reactions. ...
A PEX5 missense allele preferentially disrupts PTS1 cargo import into Arabidopsis peroxisomes
(American Society of Plant Biologists, Society for Experimental Biology and John Wiley & Sons Ltd., 2019-03-20)
The sorting of eukaryotic proteins to various organellar destinations requires receptors that recognize cargo protein targeting signals and facilitate transport into the organelle. One such receptor is the peroxin PEX5, ...
Mutation of the Arabidopsis LON2 peroxisomal protease enhances pexophagy
(Landes Bioscience, 2014)
Peroxisomes are critical organelles housing various, often oxidative, reactions. Pexophagy, the process by which peroxisomes are selectively targeted for destruction via autophagy, is characterized in yeast and mammals but ...
