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

Rcas_2887RNA polymerase, sigma 70 subunit, RpoD family; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (351 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.906
rpoC
DNA-directed RNA polymerase, beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.884
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Belongs to the DnaG primase family.
  
 0.883
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.881
Rcas_1325
TIGRFAM: methylated-DNA--protein-cysteine methyltransferase; PFAM: methylguanine DNA methyltransferase ribonuclease domain protein; Methylated-DNA-[protein]-cysteine S-methyltransferase DNA binding; KEGG: rrs:RoseRS_3679 methylated-DNA--protein-cysteine methyltransferase.
  
   0.857
lepA
GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.
 
  
 0.681
mnmE
tRNA modification GTPase TrmE; Exhibits a very high intrinsic GTPase hydrolysis rate. Involved in the addition of a carboxymethylaminomethyl (cmnm) group at the wobble position (U34) of certain tRNAs, forming tRNA- cmnm(5)s(2)U34; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. TrmE GTPase family.
     
 0.638
frr
Ribosome recycling factor; Responsible for the release of ribosomes from messenger RNA at the termination of protein biosynthesis. May increase the efficiency of translation by recycling ribosomes from one round of translation to another; Belongs to the RRF family.
 
  
 0.632
nusA
NusA antitermination factor; Participates in both transcription termination and antitermination.
 
 
 0.614
Rcas_2888
PFAM: protein of unknown function DUF58; KEGG: rrs:RoseRS_3160 protein of unknown function DUF58.
       0.587
