"SYNGTS_2057" - RNA polymerase sigma factor in Synechocystis sp. PCC6803
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SYNGTS_2057RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released (345 aa)    
Predicted Functional Partners:
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 (1102 aa)
 
 
  0.988
gyrB
DNA gyrase B subunit; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner (1078 aa)
 
 
  0.924
recG
DNA recombinase; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3’- to 5’- polarity. Unwinds branched duplex DNA (Y-DNA) (By similarity) (831 aa)
   
 
  0.912
alaS
alanyl-tRNA synthetase; Catalyzes the attachment of alanine to tRNA(Ala) in a two-step reaction- alanine is first activated by ATP to form Ala- AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain (877 aa)
   
 
  0.909
mutS2
DNA mismatch repair protein; Endonuclease that is involved in the suppression of homologous recombination and may therefore have a key role in the control of bacterial genetic diversity (822 aa)
   
      0.903
clpC
ATP-dependent Clp protease regulatory subunit (821 aa)
   
 
  0.898
clpB1
ClpB protein; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity) (898 aa)
   
 
  0.898
crhR
ATP-dependent RNA helicase DeaD; An ATP-dependent bidirectional RNA helicase with RNA- dependent ATPase activity; does not unwind dsDNA, uses only (d)ATP (PubMed-15542859). Also has ATP-dependent RNA annealing activity; concurrent annealing and helicase activity promote strand-exchange activity (PubMed-15542859). In vitro has low helicase processivity, annealing processivity is probably higher (PubMed-15542859). Required for correct cold adaptation, probably by aiding translation of mRNAs required for photosynthesis and electron transport (PubMed-22575444). Probably regulates the cold- [...] (492 aa)
   
 
  0.897
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates (314 aa)
 
 
  0.894
cph2
Hypothetical protein; Photoreceptor which exists in two forms that are reversibly interconvertible by light- the R form that absorbs maximally in the red region of the spectrum and the FR form that absorbs maximally in the far-red region (1276 aa)
   
 
  0.893
