"ntcB" - Transcriptional activator protein NtcB in Synechocystis sp. PCC6803
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

ntcBTranscriptional activator protein NtcB; Seems to regulate utilization of fixed nitrogen by controlling the expression of a certain gene(s) involved in nitrogen metabolism (309 aa)    
Predicted Functional Partners:
ntcA
Global nitrogen regulator; Required for full expression of proteins subject to ammonium repression. Transcriptional activator of genes subject to nitrogen control (225 aa)
   
     
  0.885
nirA
Ferredoxin--nitrite reductase (502 aa)
         
  0.847
glnA
Glutamate--ammonia ligase (473 aa)
           
  0.835
narB
Nitrate reductase; Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria (714 aa)
           
  0.790
nrtA
Nitrate transport 45kD protein; Essential component of the nitrate-transporting system. May be the substrate-binding protein (By similarity) (446 aa)
           
  0.787
nrtC
Nitrate transport protein subunit NrtC; Probably part of a high-affinity binding-protein- dependent transport system for nitrate. Probably responsible for energy coupling to the transport system (670 aa)
 
     
  0.742
sll1082
Nitrate transport protein subunit NrtD; Probably part of a high-affinity binding-protein- dependent transport system for nitrate. Probably responsible for energy coupling to the transport system (266 aa)
         
  0.684
SYNGTS_0915
Nitrate transport protein subunit NrtD (332 aa)
         
  0.650
cmpD
Nitrate transport protein subunit NrtD; Part of the ABC transporter complex CmpABCD involved in bicarbonate transport. Responsible for energy coupling to the transport system (By similarity) (282 aa)
         
  0.649
glnB
Nitrogen regulatory protein P-II; P-II indirectly controls the transcription of the GS gene (glnA). P-II prevents NR-II-catalyzed conversion of NR-I to NR-I-phosphate, the transcriptional activator of glnA. When P-II is phosphorylated, these events are reversed. In nitrogen-limiting conditions, when the ratio of Gln to 2-ketoglutarate decreases, P- II is phosphorylated which allows the deadenylation of glutamine synthetase (GS), thus activating the enzyme (By similarity) (112 aa)
