EC 2.7.7.42 Details
EC number
2.7.7.42
Accepted name
[glutamine synthetase] adenylyltransferase
Reaction
ATP + [glutamine synthetase]-L-tyrosine = diphosphate + [glutamine synthetase]-O4-(5′-adenylyl)-L-tyrosine
Other name(s)
glutamine-synthetase adenylyltransferase, ATP:glutamine synthetase adenylyltransferase, adenosine triphosphate:glutamine synthetase adenylyltransferase, ATP:[L-glutamate:ammonia ligase (ADP-forming)] adenylyltransferase, ATP:[L-glutamate:ammonia ligase (ADP-forming)]-L-tyrosine adenylyltransferase, [glutamate—ammonia-ligase] adenylyltransferase
Systematic name
ATP:[glutamine synthetase]-L-tyrosine adenylyltransferase
CAS registry number
9077-66-1
Comment
This bacterial enzyme adenylates a tyrosine residue of EC 6.3.1.2, glutamine synthetase. The enzyme is bifunctional, and also catalyses a reaction that removes the adenyl group from the modified tyrosine residue (cf. EC 2.7.7.89, [glutamine synthetase]-adenylyl-L-tyrosine phosphorylase) [7,8]. The two activities are present on separate domains.
