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.

cshBATP-dependent RNA helicase; DEAD-box RNA helicase that plays a role in 70S ribosome assembly. May work in conjunction with the cold shock proteins to ensure proper initiation of transcription at low and optimal temperatures. (438 aa)    
Predicted Functional Partners:
nfo
Type IV apurinic/apyrimidinic endonuclease; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate.
  
  
 0.944
pnpA
Polynucleotide phosphorylase (PNPase); Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Necessary for competence development in Bacillus subtilis. May be necessary for modification of the srfA transcript (stabilization or translation activation).
  
 
 0.873
pksJ
Polyketide synthase of type I; Involved in some intermediate steps for the synthesis of the antibiotic polyketide bacillaene which is involved in secondary metabolism.
   
 0.802
rplC
Ribosomal protein L3 (BL3); One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit (By similarity). Strongly stimulates 23S rRNA precursor processing by mini-ribonuclease 3 (MrnC); 20-30% DMSO can replace L3, suggesting the protein may alter rRNA conformation; Belongs to the universal ribosomal protein uL3 family.
   
 
 0.779
rplD
Ribosomal protein L4; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.
   
 0.761
fusA
Elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome (By similarity).
   
 0.757
recQ
ATP-dependent DNA helicase; Probable DNA helicase. Required in synaptic and/or post- synaptic stages of recombination. Probably has overlapping function with RecQ (AC O34748). It probably acts to help generate ss-DNA from ds-DNA breaks.
 
   0.746
cspD
Cold-shock protein, molecular chaperone, RNA-helicase co-factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor.
  
 0.739
cspB
Major cold-shock protein, RNA helicase co-factor, RNA co-chaperone; Binds to the pentamer sequences ATTGG and CCAAT with highest affinity in single-stranded DNA, and also to other sequences. Has greater affinity for ATTGG than CCAAT. Can act as transcriptional activator of cold shock genes by recognizing putative ATTGG-box elements present in promoter regions of genes induced under cold shock conditions.
  
 0.737
ppiB
Peptidyl-prolyl isomerase; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides; Belongs to the cyclophilin-type PPIase family.
