| Open AccessGreater efficiency of photosynthetic carbon fixation due to single amino-acid substitution
Phosphoenolpyruvate carboxylase, the key enzyme of C4 photosynthesis, evolved from an ancestral isoform in C3 plants and has a reduced feedback inhibition. Paulus et al.show that enhanced inhibitor tolerance of C4 phosphoenolpyruvate carboxylase is achieved by a single amino-acid exchange.
