(glutamate—ammonia-ligase) adenylyltransferase

Template:Short description Template:Correct title Template:Infobox enzyme In enzymology, a [glutamate—ammonia-ligase] adenylyltransferase (Template:EC number) 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.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code Template:PDB link.
