(glutamate-ammonia-ligase) adenylyltransferase

In enzymology, a [glutamate-ammonia-ligase] adenylyltransferase (EC number|2.7.7.42) is an enzyme that catalyzes the chemical reaction

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

Thus, the two substrates of this enzyme are ATP and ] , whereas its two products are diphosphate and ] .

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.

tructural studies
