[glutamine synthetase]-O4-(5'-adenylyl)-L-tyrosine:phosphate adenylyltransferase
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.
