This study was aimed at elucidating the significance of photorespiratory serine (Ser) production for cysteine (Cys) biosynthesis. For this purpose, sulfur (S) metabolism and its crosstalk with nitrogen (N) and carbon (C) metabolism were analyzed in w

Subcellular compartmentalization confers evolutionary advantage to eukaryotic cells but entails the need for efficient interorganelle communication. Malate functions as redox carrier and metabolic intermediate. It can be shuttled across membranes thr

Isolation of Plant Mitochondria Using Affinity Purification

Autor: Franziska, Kuhnert, Andreas P M, Weber

Publikováno v: Methods in molecular biology (Clifton, N.J.). 2363

Mitochondria are highly dynamic organelles that are vital for eukaryotic cellular metabolism. Mitochondria account only for a small fraction of the total cell volume. As such, intact organelle isolation is a basic requirement to study mitochondrial b

Photosynthesis in plant cells would not be possible without the supportive role of mitochondria. However, isolating mitochondria from plant cells for physiological and biochemical analyses is a lengthy and tedious process. Established isolation proto

GENOMES UNCOUPLED 4 (GUN4) is a positive regulator of light-dependent chlorophyll biosynthesis. GUN4 activates Mg chelatase (MgCh) that catalyzes the insertion of an Mg2+ ion into protoporphyrin IX. We show that Arabidopsis (Arabidopsis thaliana) GUN
