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

glnEBifunctional glutamine-synthetase adenylyltransferase/deadenyltransferase; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of [...] (947 aa)    
Predicted Functional Partners:
gltB
Catalyzes the formation of glutamate from glutamine and alpha-ketoglutarate; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.817
glnD
protein-PII uridylyltransferase; Modifies, by uridylylation and deuridylylation, the PII regulatory proteins (GlnB and homologs), in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen metabolism.

KGM28382.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.762
glnA
Forms a homododecamer; forms glutamine from ammonia and glutamate with the conversion of ATP to ADP and phosphate; also functions in the assimilation of ammonia; highly regulated protein controlled by the addition/removal of adenylyl groups by adenylyltransferase from specific tyrosine residues; addition of adenylyl groups results in inactivation of the enzyme; Derived by automated computational analysis using gene prediction method: Protein Homology.

hldE
Heptose 1-phosphate adenyltransferase; Catalyzes the ADP transfer from ATP to D-glycero-beta-D- manno-heptose 1-phosphate, yielding ADP-D-glycero-beta-D-manno-heptose. In the N-terminal section; belongs to the carbohydrate kinase PfkB family.
