CAS Registry Number 9077-66-1
Comments 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.

History
Reactions Atp + [glutamine synthetase]-L-tyrosine = diphosphate + [glutamine synthetase]-O(4)-(5′-adenylyl)-L-tyrosine.
