متن کاملDual targeting and function of a protease in mitochondria and chloroplasts.
Here we show, using the green fluorescent protein (GFP) fusion system, that an Arabidopsis thaliana zinc-metalloprotease (AtZn-MP) is targeted to both mitochondria and chloroplasts. A deletion mutant lacking the amino-terminal 28 residues, with translation initiation at the second methionine residue, was imported into chloroplasts only. However, a mutated form of the full-length targeting pepti...
متن کاملDual targeting of yeast catalase A to peroxisomes and mitochondria.
Yeast catalase A (Cta1p) contains two peroxisomal targeting signals (SSNSKF) localized at its C-terminus and within the N-terminal third of the protein, which both can target foreign proteins to peroxisomes. In the present study we demonstrated that Cta1p can also enter mitochondria, although the enzyme lacks a classical mitochondrial import sequence. Cta1p co-targeting was studied in a catalas...
متن کاملSpecific targeting of proteins to outer envelope membranes of endosymbiotic organelles, chloroplasts, and mitochondria
Chloroplasts and mitochondria are endosymbiotic organelles thought to be derived from endosymbiotic bacteria. In present-day eukaryotic cells, these two organelles play pivotal roles in photosynthesis and ATP production. In addition to these major activities, numerous reactions, and cellular processes that are crucial for normal cellular functions occur in chloroplasts and mitochondria. To func...
متن کاملArabidopsis thaliana GLN2-encoded glutamine synthetase is dual targeted to leaf mitochondria and chloroplasts.
In higher plants, photorespiratory Gly oxidation in leaf mitochondria yields ammonium in large amounts. Mitochondrial ammonium must somehow be recovered as glutamate in chloroplasts. As the first step in that recovery, we report glutamine synthetase (GS) activity in highly purified Arabidopsis thaliana mitochondria isolated from light-adapted leaf tissue. Leaf mitochondrial GS activity is furth...
