EC 2.7.7.89 Details
show Brenda entryEC number
2.7.7.89
Accepted name
[glutamine synthetase]-adenylyl-L-tyrosine phosphorylase
Reaction
[glutamine synthetase]-O4-(5′-adenylyl)-L-tyrosine + phosphate = [glutamine synthetase]-L-tyrosine + ADP
Other name(s)
adenylyl-[glutamine—synthetase]-deadenylase,
[L-glutamate:ammonia ligase (ADP-forming)]-O4-(5′-adenylyl)-L-tyrosine:phosphate adenylyltransferase,
[glutamate—ammonia ligase]-adenylyl-L-tyrosine phosphorylase
Systematic name
[glutamine synthetase]-O4-(5′-adenylyl)-L-tyrosine:phosphate adenylyltransferase
Comment
This bacterial enzyme removes an adenylyl group from a modified tyrosine residue of EC 6.3.1.2, glutamine synthetase. The enzyme is bifunctional, and also performs the adenylation of this residue (cf. EC 2.7.7.42, [glutamine synthetase] adenylyltransferase) [3,5]. The two activities are present on separate domains.
