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

nikRNickel-responsive transcriptional regulator; Transcriptional repressor of the nikABCDE operon. Is active in the presence of excessive concentrations of intracellular nickel. (133 aa)    
Predicted Functional Partners:
yohL
Putative cytoplasmic protein; Repressor of rcnA expression. Acts by binding specifically to the rcnA promoter in the absence of nickel and cobalt. In the presence of one of these metals, it has a weaker affinity for rcnA promoter (By similarity); Belongs to the FrmR/RcnR family.
      
 0.906
yohM
Putative inner membrane protein; Efflux system for nickel and cobalt.
  
   
 0.783
zntR
MerR family; similar to E. coli putative transcriptional regulator (AAC76317.1); Blastp hit to AAC76317.1 (141 aa), 92% identity in aa 1 - 141.
      
 0.777
cueR
Putative heavy metal transcriptional repressor (MerR family); Regulates the transcription of the copA and cuiD (cueO) genes. Detects cytoplasmic copper stress and activates transcription in response to increasing copper concentrations.
      
 0.773
mntR
Putative Mn-dependent transcriptional regulator; In the presence of manganese, represses expression of mntH and mntS. Up-regulates expression of mntP (By similarity). Belongs to the DtxR/MntR family.
     
 0.717
STM0613
Putative hydrogenase protein; Similar to E. coli putative DMSO reductase anchor subunit (AAC74662.1); Blastp hit to AAC74662.1 (284 aa), 30% identity in aa 6 - 200.
  
   
 0.711
cbiK
Synthesis of vitamin B12 adenosyl cobalamide precursor; Catalyzes the insertion of Co(2+) into sirohydrochlorin as part of the anaerobic pathway to cobalamin biosynthesis; Belongs to the CbiK family.
   
  
 0.701
hypA-2
Putative hydrogenase; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase.
     
 0.626
hypA
Guanine-nucleotide binding protein in formate-hydrogenlyase system; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase.
     
 0.625
modE
Transcriptional repressor of modABCD operon (molybdate uptake); Similar to E. coli molybdate uptake regulatory protein (AAC73848.1); Blastp hit to AAC73848.1 (262 aa), 89% identity in aa 1 - 262.
