Product Name [glutamine synthetase]-adenylyl-L-tyrosine phosphorylase
Example Structure Example Structure of [glutamine synthetase]-adenylyl-L-tyrosine phosphorylase EC#: 2.7.7.89
Synonyms adenylyl(glutamine synthetase) hydrolase, adenylyl-[glutamine-synthetase] hydrolase, GlnE, hydrolase adenylyl(glutamine synthetase), [glutamate-ammonia ligase]-adenylyl-L-tyrosine phosphorylase
EC Number 2.7.7.89
CAS Registry Number
Comments 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.
