additional information

Escherichia coli

the bifunctional adenylyltransferase ATase, product of glnE, catalyzes the adenylylation of glutamine synthetase and the deadenylylation of glutamine synthetase-AMP. The adenylylation reaction is activated by PII signal transduction protein, while the deadenylylation reaction requires PII-UMP. Both of these reactions are stimulated by 2-oxoglutarate and ATP
