PEP carboxylase

(Science: enzyme) enzyme responsible for the primary fixation of carbon dioxide in c4 plants. Carboxylates PEP phosphoenolpyruvate to give oxaloacetate. Also important in crassulacean acid metabolism, since it is responsible for carbon dioxide fixation in the dark.

Re:

... be able to find it online, but your textbook is probably the best bet. It's not that hard, all you need is to look for regulation of acetyl-coa carboxylase. Ok. I found that AMP regulates synthesis of fatty acids by regulating how much malonyl is available to be used, but could that be considered ...
