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

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. (787 aa)    
Predicted Functional Partners:
glnK
Nitrogen regulatory protein P-II 1; Function of homologous gene experimentally demonstrated in an other organism; regulator; Belongs to the P(II) protein family.
 
 
 0.998
amtB
Ammonium transporter; Function of homologous gene experimentally demonstrated in an other organism; transporter.
 
   
 0.915
gltB
Glutamate synthase [NADPH] large chain (NADPH-GOGAT); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
     
 0.884
glnE
Glutamate-ammonia-ligase adenylyltransferase; 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 GlnE binds the signal transd [...]

glnA-3
Glutamine synthetase I (Glutamate--ammonia ligase I) (GSI); Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
   
 0.805
glnA-4
Glutamine synthetase; Function of strongly homologous gene; enzyme; Belongs to the glutamine synthetase family.
 
   
 0.756
glnA
Glutamine synthetase 2; Function of strongly homologous gene; enzyme; Belongs to the glutamine synthetase family.
     
 0.719
CCH86287.1
Major facilitator superfamily MFS_1; Function of strongly homologous gene; transporter.
  
     0.585
CCH88643.1
Uroporphyrinogen III synthase HEM4; Function of strongly homologous gene; enzyme.
  
   
 0.582
cobB
Cobyrinic acid A,C-diamide synthase; Catalyzes the ATP-dependent amidation of the two carboxylate groups at positions a and c of hydrogenobyrinate, using either L- glutamine or ammonia as the nitrogen source; Belongs to the CobB/CbiA family.
