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

hetRMain regulator of heterocyst differentiation HetR; Controls heterocyst differentiation. Has both a protease and a DNA-binding activity; Belongs to the peptidase S48 family. (280 aa)    
Predicted Functional Partners:
NSP_2630
Global nitrogen regulatory protein, CRP family of transcriptional regulators; Nsp2630; ORF_ID:nsp2630.
      
 0.690
NSP_22100
Heterocyst differentiation protein; Nsp22100; ORF_ID:nsp22100.
      
 0.666
nifH
Nitrogenase (molybdenum-iron) reductase and maturation protein NifH; The key enzymatic reactions in nitrogen fixation are catalyzed by the nitrogenase complex, which has 2 components: the iron protein and the molybdenum-iron protein; Belongs to the NifH/BchL/ChlL family.
      
 0.644
NSP_13290
WD-40 repeat protein; Nsp13290; ORF_ID:nsp13290.
      
 0.613
ndhK
NAD(P)H-quinone oxidoreductase chain K; NDH-1 shuttles electrons from an unknown electron donor, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory and/or the photosynthetic chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient. Cyanobacterial NDH-1 also plays a role in inorganic carbon-concentration; Belongs to the complex I 20 kDa subunit family.
      
 0.613
NSP_16180
Glutamine synthetase type I; Nsp16180; ORF_ID:nsp16180.
      
 0.613
NSP_16190
Glutamine synthetase inactivating factor IF7; Nsp16190; ORF_ID:nsp16190.
      
 0.613
clpP
ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.
      
 0.613
clpP-2
ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.
      
 0.613
mtnP
5'-methylthioadenosine phosphorylase; Catalyzes the reversible phosphorylation of S-methyl-5'- thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates; Belongs to the PNP/MTAP phosphorylase family. MTAP subfamily.
