A single serine to alanine substitution decreases bicarbonate affinity of phosphoenolpyruvate carboxylase in C(4)Flaveria trinervia

Phosphoenolpyruvate (PEP) carboxylase (PEPc) catalyzes the first committed step of C(4) photosynthesis generating oxaloacetate from bicarbonate (HCO(3)(−)) and PEP. It is hypothesized that PEPc affinity for HCO(3)(−) has undergone selective pressure for a lower K(HCO3) (K(m) for HCO(3)(−)) to increa...
