Light regulates the stability of the ternary complex through the ferredoxin–thioredoxin system Regulation of chloroplast phosphoribulokinase and glyceraldehyde-3-phosphate dehydrogenase. Chloroplasts contain two isoforms of glyceraldehyde3-phosphate dehydrogenases, named A4 and A2B2. Which of the following statement about isoform of glyceraldehyde3-phosphate dehydrogenases is False?

#Unit 6. System Physiology – Plant
  1. The A4 isoform is a catalytically active tetramer
  2. The A and B polypeptides of the A2B2 isoform are similar except that a C-terminal extension of the subunit B holds two cysteines able to form a disulfide bridge
  3. The A2B2 glyceraldehyde-3-phosphate dehydrogenase can form the A8B8 oligomer can form in the light
  4. “dark conditions” the interaction of oxidized phosphoribulokinase with the A4-glyceraldehyde3-phosphate dehydrogenase and oxidized CP12 stabilizes the complex
