  2. Structure-Function Studies on Two Phosphoenolpyruvate Carboxylases

    Dharmarajan, LakshmiVirginia Tech2010

    Phosphoenolpyruvate carboxykinase (PEPCK) and phosphoenolpyruvate carboxylase (Pepc) are two important CO₂-fixation enzymes which share a similar reaction mechanism. Both operate through a lid-gated active site and have a hypothesized enol-pyruvate intermediate in their catalytic pathway. While …
