Pyruvate-Derived Amino Acids in Spinach Chloroplasts : Synthesis and Regulation during Photosynthetic Carbon Metabolism.

A probable carbon flow from the Calvin cycle to branched chain amino acids and lipids via phosphoenolpyruvate (PEP) and pyruvate was examined in spinach (Spinacia oleracea) chloroplasts. The interpendence of metabolic pathways in and outside chloroplasts as well as product and feedback inhibition were studied. It was shown that alanine, aromatic, and small… CONTINUE READING
