RESUMO
Comparison of enzyme activities in crude extracts of methylamine-grown Pseudomonas MA (ATCC 23319) to those in succinate-grown cells indicates the involvement of an acetyl coenzyme A-independent phosphoenolpyruvate carboxylase in one-carbon metabolism. The purified phosphoenolpyruvate carboxylase is activated specifically by reduced nicotinamide adenine dinucleotide (KA = 0.2 mM). The regulatory properties of this enzyme suggests that phosphoenolpyruvate serves as a focal point for both carbon assimilation and energy metabolism.
