Glutamine synthetase (GS) features prominently in bacterial nitrogen assimilation as it
catalyzes the entry of bioavailable nitrogen in form of ammonium into cellular metabolism …

Many different measurements of enzymes are undertaken to acquire different types of
information. For example, the presence of genes for an enzyme has been used to infer …

To understand the enhanced ability of marine diatoms to assimilate nitrogen (N), we
measured changes in the transcript abundance and enzyme activity of glutamine synthetase …

In the plant pathogenic ascomycete Fusarium fujikuroi the synthesis of several economically
important secondary metabolites (SM) depends on the nitrogen status of the cells. Of these …
