STRINGSTRING
glnD protein (Klebsiella pneumoniae) - STRING interaction network
"glnD" - Bifunctional uridylyltransferase/uridylyl-removing enzyme in Klebsiella pneumoniae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

glnDBifunctional uridylyltransferase/uridylyl-removing enzyme; 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 (887 aa)    
Predicted Functional Partners:
JG24_18895
Nitrogen regulatory protein P-II; Indirectly regulates nitrogen metabolism; at high nitrogen levels P-II prevents the phosphorylation of NR-I, the transcriptional activator of the glutamine synthetase gene (glnA); at low nitrogen levels P-II is uridylylated to form PII-UMP and interacts with an adenylyltransferase (GlnE) that activates GlnA; Derived by automated computational analysis using gene prediction method- Protein Homology (112 aa)
 
  0.958
JG24_21745
Catalyzes the ATP-dependent addition of AMP to a subunit of glutamine synthetase; also catalyzes the reverse reaction - deadenylation; adenylation/deadenylation of glutamine synthetase subunits is important for the regulation of this enzyme; Derived by automated computational analysis using gene prediction method- Protein Homology (945 aa)
   
   
  0.882
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 (469 aa)
 
   
  0.872
dapD
2,3,4,5-tetrahydropyridine-2,6-dicarboxylate N-succinyltransferase; Catalyzes the formation of N-succinyl-2-amino-6-ketopimelate from succinyl-CoA and tetrahydrodipicolinate in the lysine biosynthetic pathway; Derived by automated computational analysis using gene prediction method- Protein Homology; Belongs to the transferase hexapeptide repeat family (274 aa)
       
  0.830
JG24_04330
Indirectly regulates nitrogen metabolism; at high nitrogen levels P-II prevents the phosphorylation of NR-I, the transcriptional activator of the glutamine synthetase gene (glnA); at low nitrogen levels P-II is uridylylated to form PII-UMP and interacts with an adenylyltransferase (GlnE) that activates GlnA; Derived by automated computational analysis using gene prediction method- Protein Homology (112 aa)
 
 
  0.804
JG24_30370
Methionine aminopeptidase; Catalyzes the removal of N-terminal amino acids from peptides and arylamides; generally Co(II) however activity has been shown for some methionine aminopeptidases with Zn, Fe, or Mn; Derived by automated computational analysis using gene prediction method- Protein Homology (264 aa)
