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

glnDPutative 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 fixation and metabolism. (861 aa)    
Predicted Functional Partners:
glnB
PII-like signal transmitter proteins are involved in the regulation of ammonium assimilation and nitrogen fixation. The PII-like proteins differed from each other in details of N-sensing. They were covalently modified by uridylylation upon nitrogen limitation. Similar to trembl|Q9EZQ2 (100%) and to trembl|Q8XWX5 (82%). Pfam: Nitrogen regulatory protein P-II; High confidence in function and specificity.

glnK
PII-like signal transmitter proteins are involved in the regulation of ammonium assimilation and nitrogen fixation. The PII-like proteins differed from each other in details of N-sensing. They were covalently modified by uridylylation upon nitrogen limitation. Similar to trembl|Q9EZQ3 (100%) and to trembl|Q7NQY3 (87%). Pfam: Nitrogen regulatory protein P-II; High confidence in function and specificity.

glnY
PII-like signal transmitter proteins are involved in the regulation of ammonium assimilation and nitrogen fixation. The PII-like proteins differed from each other in details of N-sensing. They were covalently modified by uridylylation upon nitrogen limitation. Similar to trembl|Q9EZQ4 (100%) and to trembl|Q9RBK0 (78%). Pfam: Nitrogen regulatory protein P-II; High confidence in function and specificity.

Methionyl aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.

glnE
Probable [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 si [...]
