In enzymology a [glutamate—ammonia-ligase] adenylyltransferase (EC 2.7.7.42) is an enzyme that catalyzes the chemical reactionATP + [L-glutamate:ammonia ligase (ADP-forming)] 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).
