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

AFY55785.1RNA polymerase sigma factor, cyanobacterial RpoD-like family; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (327 aa)    
Predicted Functional Partners:
AFY55374.1
Putative transcriptional regulator; PFAM: MerR family regulatory protein.
   
   0.872
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.856
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.
 
 
 0.821
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.
  
 
 0.819
rpoZ
DNA-directed RNA polymerase, subunit K/omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
   
 
 0.716
trmD
tRNA (guanine-N1)-methyltransferase; Specifically methylates guanosine-37 in various tRNAs. Belongs to the RNA methyltransferase TrmD family.
 
    0.670
secA
Protein translocase subunit secA; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
 
 
 0.647
AFY57818.1
GTP-binding protein LepA; PFAM: Elongation factor Tu domain 2; Elongation factor G C-terminus; Elongation factor Tu GTP binding domain; GTP-binding protein LepA C-terminus; TIGRFAM: GTP-binding protein LepA; small GTP-binding protein domain.
 
  
 0.582
rplS
Ribosomal protein L19; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
 
   
 0.579
prfA
Bacterial peptide chain release factor 1 (bRF-1); Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA.
