STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

glnAGlutamine synthetase; Carries out the ATP-dependent synthesis of glutamine from ammonium nitrogen and glutamate. Exhibits both L-gamma- glutamylhydroxamate synthetase and gamma-glutamyltransferase activities when using hydroxylamine as substrate; in fact, the enzyme possesses low biosynthetic activity, suggesting that the reaction is biased towards the degradation of glutamine under ammonia-rich conditions. Might play some role in ammonia assimilation under ammonia-starvation conditions. Can also use GTP instead of ATP in the synthetase reaction, but not CTP or UTP. (443 aa)    
Predicted Functional Partners:
glmS
Glucosamine--fructose-6-phosphate aminotransferase (isomerizing); Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source.

purQ
Phosphoribosylformylglycinamidine synthase I; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist i [...]
