How does a trifecta key box work
WebInside the cell, malic acid is formed from phosphoenolpyruvate (PEP) through the activities of phosphoenolpyruvate carboxylase (PEPC) and malate dehydrogenase (MDH) , and cytosolic malate is transported to and sequestered in the vacuole . Malate can be degraded by the reversible reaction of MDH and NADP-malic enzyme (NADP-ME). WebA. Phosphoenolpyruvate Carboxylase. Phosphoenolpyruvate (PEP) carboxylase requires Mg2+, and the carboxylating agent is HCO 3−. The carboxylating agent was determined by incubation of the enzyme with PEP and HC 18 O 3− and showing that no H 218 O is formed. If CO 2 were the carboxylating agent, the HC 18 O 3− would have had to lose H 18 O ...
