Title: Physical interaction of plant TCA cycle enzymes – additional way
for metabolic regulation?
Speaker: Toshihiro Obata
Affiliation: Max Planck Institute Molecular Plant Physiology, Potsdam-Golm, Germany
Abstract:
Plant mitochondrial tricarboxylic acid (TCA) cycle is operated in drastically different flux modes depending on the environment especially on the availability of light unlike that of heterotrophic organisms. Although some post-translational enzymatic regulation including allosteric regulation, phosphorylation and redox regulation have been proposed, molecular basis of plant TCA cycle regulation is still largely elusive. It has long been known that TCA cycle enzymes of animals, yeast and bacteria form multi-enzyme complexes and channel a reaction product to the enzyme mediating next reaction. Such a protein complex is called as “metabolon” and is considered as an important component of metabolic regulation. Our recent attempt to elucidate plant TCA cycle "metabolon" and its impact on plant cellular metabolism would be presented in this talk.
