STRINGSTRING
ntcA protein (Synechocystis sp. PCC6803) - STRING interaction network
"ntcA" - Global nitrogen regulator 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

ntcAGlobal nitrogen regulator; Required for full expression of proteins subject to ammonium repression. Transcriptional activator of genes subject to nitrogen control (225 aa)    
Predicted Functional Partners:
glnA
Glutamate--ammonia ligase (473 aa)
           
  0.982
narB
Nitrate reductase; Nitrate reductase is a key enzyme involved in the first step of nitrate assimilation in plants, fungi and bacteria (714 aa)
           
  0.967
nirA
Ferredoxin--nitrite reductase (502 aa)
           
  0.966
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)
           
  0.957
ureA
Urease gamma subunit (100 aa)
           
  0.945
ssl0105
Hypothetical protein (88 aa)
       
 
  0.896
dctP
C4-dicarboxylase binding protein (369 aa)
           
  0.892
ntcB
Transcriptional 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)
   
     
  0.885
cynS
Cyanate lyase; Catalyzes the reaction of cyanate with bicarbonate to produce ammonia and carbon dioxide (149 aa)
           
  0.877
cbbL
Ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit; RuBisCO catalyzes two reactions- the carboxylation of D- ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site (470 aa)
