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.

ninInhibitor of the DNA degrading activity of NucA (competence); Plays a role in the competence of cells to be transformed. It inhibits the activity of the DNA-entry nuclease. (132 aa)    
Predicted Functional Partners:
nucA
Endonuclease; By degrading DNA that enters the cell, plays a role in the competence of cells to be transformed. Degrades both double-stranded, linear and covalently closed circular DNA.
  
  
 0.995
nucB
Nuclease; Degrades both double-stranded linear and covalently closed circular DNA. Likely to play a scavenging role in order to supply nutrients under starvation conditions; To B.subtilis NucA/ComI.
  
  
 0.886
tlpC
Methyl-accepting chemotaxis protein; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; receptor.
  
  
 0.862
glnP
Glutamine ABC transporter (permease); Part of the ABC transporter complex GlnHMPQ involved in glutamine transport. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family.
   
  
 0.744
comFB
Conserved hypothetical protein; Evidence 1a: Function experimentally demonstrated in the studied strain; PubMedId: 16009133, 8045879, 8412657.
   
    0.727
ssbB
Single-strand DNA-binding protein; Not essential for replication of the chromosome, but is required for optimal competence. Binds ssDNA, binding is facilitated by DprA, acts as an accessory factor for homologous DNA strand exchange.
   
    0.726
comFA
Helicase competence protein; Involved in transformation (competence for DNA uptake). Required for DNA uptake but not for binding. May provide the driving force for transport of DNA through an aqueous channel. Belongs to the helicase family.
   
    0.722
comFC
Putative component of the DNA transport apparatus; Involved in transformation (competence for DNA uptake).
   
    0.703
comGE
Component of the DNA transport platform; Required for transformation and DNA binding.
   
    0.701
comGF
Component of the DNA transport platform; Required for transformation and DNA binding.
   
    0.663
