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:
some 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

trmDTrna m(1)g37 methyltransferase, sam-dependent; Specifically methylates guanosine-37 in various tRNAs (255 aa)    
Predicted Functional Partners:
rimM
One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late assembly stage of the 30S ribosomal subunit. An accessory protein needed during the final step in assembly of the 30S ribosomal subunit, for assembly of the head region (the 16S rRNA 3' domain) It may act while Era is associated and before RimP in 30S subunit assembly . Interacts with S19 . Essential for efficient processing of 16S rRNA; a deletion mutant accumulates 17S rRNA . Deletions also do not assemble the head-associated ribosomal proteins correctly . May be needed both before and after RbfA durin [...]

rpsP
Small subunit ribosomal protein s16; In addition to being a ribosomal protein, S16 also has a cation-dependent endonuclease activity
  
 0.999
rplS
This protein is located at the 30S-50S ribosomal subunit interface. In the 70S ribosome it has been modeled to make two contacts with the 16S rRNA of the 30S subunit forming part of bridges B6 and B8 . In the 3.5 A resolved structures L14 and L19 interact and together make contact with the 16S rRNA . The protein conformation is quite different between the 50S and 70S structures, which may be necessary for translocation
 
  
 0.997
rpoA
Dna-directed rna polymerase subunit alpha; DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme
 
  
 0.979
rpsB
Small subunit ribosomal protein s2; Required for ribosomal protein S1 to bind to the 30S subunit
 
  
 0.978
trmH
Trna mg18-2'-o-methyltransferase, sam-dependent; Catalyzes the 2'-O methylation of guanosine at position 18 in tRNA. Type II methylase, which methylates only a subset of tRNA species
   
 
 0.977
rpsD
Small subunit ribosomal protein s4; One of two assembly initiator proteins for the 30S subunit, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit. Plays a role in mRNA unwinding by the ribosome, possibly by forming part of a processivity clamp. Also functions as a rho-dependent antiterminator of rRNA transcription, increasing the synthesis of rRNA under conditions of excess protein, allowing a more rapid return to homeostasis. Binds directly to RNA polymerase
 
  
 0.974
rpoB
Dna-directed rna polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates
 
  
 0.973
rpsH
Small subunit ribosomal protein s8; One of the primary rRNA binding proteins, it binds directly to 16S rRNA central domain where it helps coordinate assembly of the platform of the 30S subunit
  
  
 0.966
trmL
Trna leu mc34,mu34 2'-o-methyltransferase, sam-dependent; Methylates the ribose at the nucleotide 34 wobble position in the two leucyl isoacceptors tRNA(Leu)(CmAA) and tRNA(Leu)(cmnm5UmAA). Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH of the wobble nucleotide. Recognition of the target requires a pyridine at position 34 and N(6)-(isopentenyl)-2-methylthioadenosine at position 37
