摘要:
Phosphoenolpyruvate carboxylase (PEPC) characterized by a specific activity of at least 40 units/mg; and/or by no more than 50% loss of activity after 60 days in 167 mM Tricine/HCl buffer, pH 8.0, and 15 mM MgCl.sub.2 ; and/or, at pH 6.5, an activity of at least 40% relative to the activity at optimum pH is disclosed. Such enzymatic activity can be obtained from serine pathway methylotrophs such as Hyphomicorbium, and is very suitable for use in measuring bicarbonate in biological samples.
