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

yfmLPutative ATP-dependent RNA helicase; A probable DEAD-box RNA helicase that plays a role in ribosomal 50S subunit assembly. May be a non-specific RNA helicase. Belongs to the DEAD box helicase family. (376 aa)    
Predicted Functional Partners:
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).
  
 
 0.842
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).
   
 0.807
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.
 
 0.799
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.
   
 
 0.786
rplM
Ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
  
 0.756
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.
   
 0.753
rplX
Ribosomal protein L24 (BL23); One of two assembly initiator proteins, it binds directly to the 5'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit. Has also been isolated as a basic, heat-shock stable DNA- binding protein from the B.subtilis nucleoid. It binds cooperatively to double-stranded supercoiled DNA which it further compacts into complexes 15-17 nm in diameter. Overexpression of the protein disrupts nucleoid segregation and positioning.
   
 
 0.745
atpD
ATP synthase (subunit beta, component F1); Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits; Belongs to the ATPase alpha/beta chains family.
   
 
 0.717
rplO
Ribosomal protein L15; Binds to the 23S rRNA; Belongs to the universal ribosomal protein uL15 family.
   
 
 0.710
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.
