A novel assay of
CTP synthetase
was developed which allows the processing of large numbers of samples. The amount of glutamate produced by
CTP synthetase
was determined with
glutamate dehydrogenase
and the NAD analogue acetyl-pyridine-adenine dinucleotide was used to shift the initial unfavourable equilibrium towards the formation of a-ketoglutarate. The amount of glutamate determined with the assay was comparable to that of CTP. The assay proved to be linear with time up to 90 min and protein concentrations up to 520 micrograms/ml. However, at low protein concentrations as well as at early time points a lag phase was observed. This hysteretic phenomenon of
CTP synthetase
may be due to the association-dissociation equilibrium that exists between the various polymerisation states of the enzyme.
