In enzymology, a [glutamate-ammonia-ligase] adenylyltransferase () is an enzyme that catalyzes the chemical reaction

ATP + [L-glutamate:ammonia ligase (ADP-forming)] \rightleftharpoons diphosphate + adenylyl-[L-glutamate:ammonia ligase (ADP-forming)]

Thus, the two substrates of this enzyme are ATP and [L-glutamate:ammonia ligase (ADP-forming)], whereas its two products are diphosphate and adenylyl-[L-glutamate:ammonia ligase (ADP-forming)].

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is ATP:[L-glutamate:ammonia ligase (ADP-forming)] adenylyltransferase. Other names in common use include glutamine-synthetase adenylyltransferase, ATP:glutamine synthetase adenylyltransferase, and adenosine triphosphate:glutamine synthetase adenylyltransferase.
